This story was updated at 10:45 a.m. on Sept. 22.

ATLANTA —  A key vaccine advisory panel at the Centers for Disease Control and Prevention has indefinitely postponed a controversial change to guidelines on administering hepatitis B vaccines to newborn babies, and altered long-standing recommendations around COVID-19 vaccine access for children and adults, though a proposal to require prescriptions for all individuals seeking the shot narrowly failed. 

The panel also voted to reverse a decision they made only Thursday that would have prevented updated guidelines on the MMRV vaccine, which protects against measles, mumps, rubella and varicella, from applying to children enrolled in the Vaccines for Children program. 

Vaccines for Children is a federal program which covers the cost of vaccines for more than half of American children. The decision to implement different standards for children enrolled in VFC caused confusion among top health officials as well as some committee members when it was introduced Thursday. 

Jason Goldman, the president of the American College of Physicians who also serves as a liaison to the committee, criticized Thursday’s vote, arguing that the changes were not backed by scientific evidence. 

“Would you consider that the second vote actually revealed the truth, that you do not have the data or evidence to challenge the current standing and that there is no associated harm?” Goldman asked the committee.

The committee’s reversal on Friday standardizes the updated MMRV vaccine recommendations for all children. If ACIP’s recommendations are approved by CDC officials, doctors will be advised to administer separate MMR and varicella vaccines for all children under 4 years of age.

ACIP tables a rule delaying Hepatitis B vaccine for newborns

In what appeared to be another reversal, the panel shelved a resolution that sought to alter current CDC recommendations around hepatitis B vaccines for newborn children. 

The current three-dose series for hepatitis B, an incurable viral infection that attacks the liver, includes one vaccine administered to infants within 24 hours of birth, and subsequent booster shots given a month and six months after the initial dose. ACIP has been recommending a hepatitis B vaccine for all newborn babies since 1991, which resulted in a 99% drop in serious infections between 1990 and 2019.

If ACIP members choose to implement the changes at a later meeting, official CDC guidelines will recommend that pediatricians delay administering the first dose of the hepatitis B vaccine until 30 days after birth for all children whose mothers test negative for the disease.

The panel did not provide any evidence indicating that delaying the vaccine improved children’s health, or that there were any widespread or serious instances of harm caused by administering hepatitis B vaccines to newborns. However, some ACIP members also cast doubt on the accuracy of data showing the shot is safe.

“I think that there are gaps in what we know and understand about the effects of hepatitis B, particularly on very young infants,” said Vicky Pebsworth, a committee member who is a registered nurse and who sits on the board of the National Vaccine Information Center, which advocates for vaccine exemptions. “I think that the conclusion that we know that it is safe is, perhaps, premature.” 

Dr. Adam Langer, who serves as the principal deputy director of the CDC’s National Center for HIV, Viral Hepatitis, STD, and Tuberculosis Prevention, urged the panel to reconsider narrowing the recommendations.

“One of the primary reasons for recommending universal birth dose in the U.S. is to serve as a safety net for infants born to mothers with unknown test results,” Langer said during his presentation to the committee on Thursday. 

“To date, no country in the world has reverted from universal to selective birth dose recommendations,” he added.

The meeting, which was held at the CDC’s Chamblee campus, also inspired a demonstration organized by a group of former CDC workers, who dressed up as preventable diseases and waved signs to the passing cars while the meeting was underway. 

Cindy Weinbaum, who spent about a decade of her career at the CDC in the division of viral hepatitis, said she commended the committee for deciding to table a vote that would have changed the recommendations for hepatitis B vaccinations.

“I think it’s really commendable, actually, that they delayed this vote because they do not know the implications of not recommending a birth dose of hepatitis B,” Weinbaum said.

“So that was a nod to their lack of understanding of vaccine programs, vaccine science and the importance of certain vaccinations for kids,” she added.

Weinbaum said the proposal’s appearance on the committee’s agenda reflects the “vaccine nihilism that the current administration is supporting.” She said the shot given to newborns within the first day of their life has found itself in the “cross hairs of the anti-vax movement.”

“It’s because here’s this newborn baby and you’re very vulnerable, and sticking it with a needle is kind of a scary thing,” she said. “They just don’t understand that it’s even more scary to get liver cancer, and that’s really what we want to prevent.”

ACIP moves to center vaccine harm

Though the committee did not implement some of its more controversial proposals, ACIP’s new members have signaled that they would like to place a greater focus on examples of vaccine harm and adverse outcomes in future policy proposals.

They have also rejected widely embraced data on vaccine safety, choosing instead to focus on isolated cases and dubious studies, including one paper claiming that rats exposed to the COVID-19 vaccine exhibited “autism-like behaviors” that was eventually retracted by the journal that published it.

Some ACIP members, including Robert Malone, also pushed back against guidelines that advise vaccinating young children and pregnant women, arguing that there is a lack of data proving definitively that vaccines are safe. 

“The default should be the assumption that there is no intervention in the infant and the pregnant woman with the vaccine unless there is definitive evidence of safety,” Malone said.

But Dr. Cody Meissner, a professor of pediatrics and medicine at Dartmouth College who has served as a past committee member, pushed back against the argument that any medical intervention should be entirely risk-free.

“I just want to point out that it’s very, very difficult to prove the absence of harm, it’s simply not a practical objective,” Meissner said.

“I think it’s important for everyone to understand that no vaccine is 100% safe and no vaccine is 100% effective,” he added. “What’s important for the provider before administering a vaccine is to think about that particular patient and does the benefit of protection exceed any possible side effect from the vaccine.” 

But in a conversation with reporters after the meeting, Retsef Levi, an ACIP member and professor of operations management at the Massachusetts Institute of Technology, signaled that the committee could revisit other vaccine recommendations in future meetings.

“I think we need to review vaccines, in general, from time to time,” Levi said. “It’s part of a good process. I don’t think that I need now to single out one vaccine or another. I think that, in general, it’s actually in the mission of ACIP. . . to actually review every vaccine.”

Georgia Recorder editor-in-chief Jill Nolin contributed to this report.

Correction: An earlier version of this story mischaracterized ACIP’s 1991 recommendation for the first dose of the hepatitis B vaccine. The 1991 recommendation was for all newborn babies to receive the shot, but not specifically within the first day of being born.

Wisconsin’s Department of Health Services is continuing to recommend that anyone over 6 months old get an updated, annual version of the COVID-19 vaccine.

Meanwhile, the state’s DHS has put out a standing order for the vaccine. State officials say that will ensure that most Wisconsinites are able to get the COVID vaccine at pharmacies across Wisconsin without a prescription. 

This year’s Wisconsin DHS guidelines mirror guidance from a broad range of medical experts. And the guidance echoes what state and federal health officials have recommended in recent years.

Wisconsin’s recommendations stand in contrast, however, to recent moves at the federal level.

This year, the federal Food and Drug Administration has approved the new COVID vaccine for Americans ages 65 and older and for people with certain higher risk conditions. At the national level, a panel is set to meet later this week to discuss vaccine recommendations that will be provided to the U.S. Centers for Disease Control and Prevention.

New U.S. Health Secretary Robert F. Kennedy Jr. is a vaccine skeptic who has promoted false information about vaccines.

Wisconsin is now one of several states where health officials have moved to take statewide action on vaccines because of worries about how federal actions could impede vaccine access.

“In the past several months, leaders at federal agencies have made policy decisions and issued recommendations that aren’t supported by or directly contradict scientific consensus,” Dr. Ryan Westergaard, a chief medical officer within DHS, said during a news conference.

The latest announcement from Wisconsin’s health department comes a day after Democratic Gov. Tony Evers issued an executive order directing the Wisconsin DHS to put out its own COVID vaccine recommendations.

The order also attempts to ensure that Wisconsinites won’t have to pay out of pocket for COVID vaccines. It says that the state Office of the Commissioner of Insurance shall “direct all health insurers within their regulatory authority to provide coverage for the COVID-19 vaccine without cost-sharing to all their insureds.”

“Vaccines save lives, folks,” Evers said in a statement accompanying his order. “RFK and the Trump Administration are inserting partisan politics into healthcare and the science-based decisions of medical professionals and are putting the health and lives of kids, families, and folks across our state at risk in the process.”

State health officials are recommending that Wisconsinites get their new COVID vaccines to coincide with the fall spike in respiratory diseases. Those shots are recommended even for people who have gotten COVID shots in the past. That’s because the vaccines released in 2025 are designed to hedge against potentially waning immunity and to target newly emerging versions of the virus, Westergaard said.

“The same way that we recommend getting your flu shot booster every year, because the flu that’s going around this year might be slightly different than the flu that was going around last year, we recommend a COVID booster,” he said.

Seeking to combat efforts of the U.S. Secretary of Health and Human Services Robert F. Kennedy Jr. and the Trump administration, Gov. Tony Evers signed an executive order Monday that is aimed at protecting access to vaccines in Wisconsin. 

“Vaccines save lives, folks. Spreading fear, distrust, and disinformation about safe and effective vaccines isn’t just reckless, it’s dangerous,” Evers said in a statement. “RFK and the Trump administration are inserting partisan politics into healthcare and the science-based decisions of medical professionals and are putting the health and lives of kids, families, and folks across our state at risk in the process.”

Kennedy in his role as the health secretary has taken aim at vaccines, including the COVID-19 vaccine. This week, a CDC committee with new members appointed by Kennedy who are skeptical of vaccines is expected to consider softening or eliminating some recommendations for the COVID-19 vaccine and some childhood immunizations. 

“Here in Wisconsin, we will continue to follow the science to ensure Wisconsinites have access to the healthcare they need when and where they need it to make their own healthcare decisions that are right for them,” Evers said. 

The order directs the state Department of Health Services to take several steps towards protecting access including monitoring and reviewing immunization recommendations, issuing guidance on the COVID-19 vaccine, determining additional measures that may be necessary to provide clarity and guidance on other routine vaccines.

The Office of the Commissioner of Insurance is also directed under the order to collaborate with health plans to make sure people have accurate, up-to-date information on access to vaccines and to help limit the costs of vaccines and to direct health insurers within their regulatory authority to provide coverage for the COVID-19 vaccine without cost-sharing.

Several states, including Colorado, Massachusetts, New Mexico, New York and Pennsylvania, announced this week that they would be breaking with restrictive eligibility policies unveiled last week by the U.S. Food and Drug Administration on the newly approved COVID-19 vaccines for the fall season.

In New York, Democratic Gov. Kathy Hochul signed an executive order Friday morning to authorize pharmacists to provide the shot to anyone who desires it for the next 30 days, which can be renewed.

“When they said that they are not going to be requiring COVID shots and other vaccinations for our families, I said, ‘No, here in New York we will make parents have the option.’ If you want your child to have a COVID shot, it should be available to you and it should be covered by insurance,” Hochul said during a news conference Friday morning, where she signed the order.

“So what I’m doing now is signing an executive order, because extreme times call for extreme measures. And this is the power I have to use in the interim until we are able to have the legislature get back in January and pass legislation that mandates this.”

Previous FDA policy recommended that COVID-19 vaccine booster shots be made available to anyone 6 months or older regardless of their health status. But in August, the federal agency announced restrictions for the new shot.

The FDA limited access to the vaccines to people who are 65 and older and to younger people with at least one underlying health condition, such as asthma or obesity, that would put them at risk of developing a severe illness without a booster shot. Children are eligible only if a medical provider is consulted. Additionally, the Pfizer vaccine, one of the three that were approved, will no longer be available for any child under 5.

“The American people demanded science, safety, and common sense. This framework delivers all three,” U.S. Health and Human Services Secretary Robert F. Kennedy Jr. wrote on social media platform X on Aug. 27.

Other states are also taking measures to ensure more people can get access to the vaccines.

On Thursday, Massachusetts Democratic Gov. Maura Healey ordered health insurers in the state to continue covering the vaccine. The state also issued an order to allow pharmacies to continue providing shots to residents above the age of 5.

Massachusetts is “leading efforts to create a public health collaboration with states in New England and across the Northeast committed to safeguarding public health as the federal government backs away from its responsibilities,” the governor’s office said in a release.

This week, the State Board of Pharmacy in Pennsylvania held a special meeting to vote to bypass federal vaccine recommendations and allow pharmacists to continue administering COVID-19 vaccines.

“Health care decisions should be up to individuals — not the federal government and certainly not RFK Jr. My Administration will continue to protect health care access for all Pennsylvanians,” Pennsylvania Democratic Gov. Josh Shapiro said.

Colorado and New Mexico took similar steps this week, with state officials signing public health orders asking state agencies to take steps necessary to require insurers to cover the vaccines and instructing pharmacists to provide the shots without a doctor’s note.

WASHINGTON — Health and Human Services Secretary Robert F. Kennedy Jr.  vehemently defended his actions on vaccines and other public health issues under questioning by both Republican and Democratic senators during a contentious hearing Thursday.

Kennedy, confirmed on a mostly party-line vote earlier this year, repeatedly justified firing everyone on an influential vaccine advisory panel, as well as the president’s decision to remove a Centers for Disease Control and Prevention director who’d served for less than a month after confirmation by the Senate.

“In your confirmation hearings, you promised to uphold the highest standards for vaccines. Since then, I’ve grown deeply concerned,” said Senate Majority Whip John Barrasso, R-Wyo. “The public has seen measles outbreaks. Leadership of the National Institutes of Health questioning the use of mRNA vaccines. The recently confirmed director of the Centers for Disease Control and Prevention fired. Americans don’t know who to rely on.”

Barrasso, an orthopedic surgeon, sought to reinforce support for vaccines to Kennedy during the Senate Finance Committee hearing, saying they “are estimated to have saved 154 million lives worldwide.”

Louisiana Republican Sen. Bill Cassidy, a physician who received several concessions from Kennedy in exchange for voting to confirm him as HHS secretary, raised numerous questions about Kennedy’s behavior. Cassidy is the chairman of the Health, Education, Labor and Pensions Committee.

Cassidy appeared to box in Kennedy on the COVID-19 vaccine by saying President Donald Trump should receive the Nobel Prize for Operation Warp Speed, which led to the development of the shot during his first term. 

Kennedy agreed Trump should “absolutely” get the prize, leading Cassidy to question why he’d taken actions as HHS secretary to erode trust and eliminate funding for vaccine development activities. 

“It surprises me that you think so highly of Operation Warp Speed when, as an attorney, you attempted to restrict access,” Cassidy said. “It also surprises me because you’ve canceled, or HHS did, but apparently under your direction, $500 million in contracts using the mRNA vaccine platform that was critical to Operation Warp Speed.”

Cassidy said the cancellation represents not only “an incredible waste of money but it also seems like a commentary upon what the president did in Operation Warp Speed, which is to create a platform by which to create vaccines.”

Cassidy also questioned Kennedy’s actions eliminating everyone on the CDC’s Advisory Committee on Immunization Practices and replacing them with his own choices. 

“If we put people who are paid witnesses for people suing vaccines, that actually seems like a conflict of interest,” Cassidy said. 

Kennedy disagreed, testifying that “it may be a bias. And that bias, if disclosed, is okay.”

Tillis asks RFK Jr. to respond in writing

North Carolina Republican Sen. Thom Tillis asked Kennedy a series of questions but said he wanted the secretary to submit his answers in writing in order to clarify several of his positions. 

“Some of your statements seem to contradict what you said in the prior hearing,” Tillis said. “You said you’re going to empower the scientists at HHS to do their job. I’d just like to see evidence where you’ve done that, and I’m sure that you will have some.”

Tillis said he wanted Kennedy to respond to reports that he’s gone back on his commitments to senators to not do anything “that makes it difficult or discourages people from taking vaccines” and that Kennedy would not “impose my belief over any of yours.”

“That, again, seems to be contradictory to the firing of the CDC director, the canceling of mRNA research contracts, firing advisory board members, attempting to stall NIH funding, eliminating funding for I think a half a billion dollars for further mRNA research,” he said, referring to the National Institutes of Health. 

Tillis said he was having difficulty understanding why former CDC Director Susan Monarez, whom Trump nominated in March and the Senate voted to confirm in late July, had been fired so quickly. 

“I don’t see how you go … from a public health expert with unimpeachable scientific credentials, a long-time champion of MAHA values, caring and compassionate and brilliant microbiologist — and four weeks later, fire her,” Tillis said. 

CDC shooting, Monarez firing probed

Georgia Democratic Sen. Raphael Warnock questioned Kennedy at length over the firing of Monarez as well as a shooting at the Atlanta-based agency this summer. 

Kennedy testified that he doesn’t believe he criticized Monarez during a meeting in late August over her comments following the CDC shooting that “misinformation can be dangerous.”

During that meeting, Kennedy said he did demand that Monarez fire career CDC scientists but testified he didn’t tell her to accept the recommendations of the vaccine advisory panel without further review.

“What I asked her about is, she had made a statement that she was going to not sign on and I wanted clarification about that,” Kennedy said. “I told her I didn’t want her to have a role if she’s not going to sign onto it.”

Monarez wrote in an op-ed published in the Wall Street Journal just hours before the hearing began that during the meeting with Kennedy she “was told to preapprove the recommendations of a vaccine advisory panel newly filled with people who have publicly expressed antivaccine rhetoric.”

“That panel’s next meeting is scheduled for Sept. 18-19,” Monarez wrote. “It is imperative that the panel’s recommendations aren’t rubber-stamped but instead are rigorously and scientifically reviewed before being accepted or rejected.”

Warnock asked Kennedy if he said that the CDC was the “most corrupt federal agency in the history of the world.” 

Kennedy testified he didn’t say that exactly but did say “it’s the most corrupt agency at HHS and maybe the government.” 

Warnock concluded his five minutes of questions telling Kennedy that “it’s clear you’re carrying out your extremist beliefs” and that he represents “a threat to the public health of the American people.”

“For the first time, we’re seeing deaths from children from measles,” Warnock said. “We haven’t seen that in two decades. We’re seeing that under your watch. You are a hazard to the health of the American people.”

Lankford, Daines ask about medication abortion

Several senators, including Oklahoma Republican James Lankford and Montana Republican Steve Daines, asked Kennedy about the ongoing review of mifepristone, one of two prescription pharmaceuticals used in medication abortion. 

Kennedy said he spoke with FDA Commissioner Marty Makary about the topic just yesterday and committed to keeping senators informed, but didn’t appear to know much more than that. 

“I don’t know if they’re going to do an insurance claim study. That’s one way to do it. I don’t know exactly whether they’re doing epidemiological studies or observational studies. I don’t know exactly what they’re doing,” Kennedy said. “But I know I talked to Marty Makary about it yesterday, and he said those studies are progressing and that they’re ongoing. So I will keep your office informed at every stage.”

Kennedy testified that he didn’t know when exactly the studies would be completed. 

The FDA first approved mifepristone in 2000 before updating the prescribing guidelines in 2016 and during the coronavirus pandemic. 

It’s currently approved for up to 10 weeks gestation and can be prescribed via telehealth and shipped to patients. Mifepristone is the first pharmaceutical of medication abortion and is typically followed by misoprostol. 

Medication abortion accounted for about 64% of all abortions in 2023, according to research from the Guttmacher Institute. 

The Supreme Court rejected an effort to limit access to medication abortion last year in a case originally filed by four anti-abortion medical organizations and four anti-abortion doctors that were represented by Alliance Defending Freedom.

Justice Brett Kavanaugh wrote the opinion that “federal conscience laws have protected pro-life doctors ever since FDA approved mifepristone in 2000.”

Numerous medical organizations, including the American College of Obstetricians and Gynecologists and the American Medical Association, wrote briefs to the Supreme Court in that case attesting to the safety and efficacy of mifepristone. 

“The scientific evidence is overwhelming: major adverse events occur in less than 0.32% of patients,” the medical organizations wrote. “The risk of death is almost non-existent.”

The Democratic governors of California, Oregon and Washington said Wednesday they are forming an alliance to coordinate vaccine recommendations for their states.

Meanwhile, Florida announced plans to become the first state to phase out all vaccine mandates, including ending requirements that kids be vaccinated against dangerous diseases before enrolling in schools.

Public health experts have relied on vaccines, including school mandates, for decades to limit the spread of communicable diseases and keep kids and adults safe.

The contrasting moves come amid turmoil at the U.S. Centers for Disease Control and Prevention, where several top leaders resigned last week to protest efforts by Health and Human Services Secretary Robert F. Kennedy Jr., a vaccine skeptic, to dismiss CDC Director Susan Monarez for pushing back against Kennedy’s vaccine policies.

Accompanied by Florida Republican Gov. Ron DeSantis, state Surgeon General Dr. Joseph A. Ladapo said at a news conference Wednesday that vaccine mandates are “wrong” and “immoral,” the Florida Phoenix reported.

“Your body is a gift from God. What you put into your body is because of your relationship with your body and your God,” Ladapo said.

“They do not have the right to tell you what you put in your body. They don’t have the right to tell you what your kids have to put in [their] body. They do not have the right. Do not give it to them. Take it away from them. And we’re going to be starting that here in Florida.”

The Florida Department of Health can eliminate some vaccine mandates on its own, Ladapo said, but the Florida legislature would have to scrap other ones. He did not mention specific vaccines, but repeated that his goal was to end “all of them. Every last one of them.”

“Every last one of them is wrong and drips with disdain and slavery,” Ladapo said.

The goal of the new West Coast Health Alliance, governors said, is to disseminate evidence-based recommendations about who should get immunized, as well as to provide vaccine education throughout the three states. In the coming weeks, the states will coordinate and finalize immunization guidelines that are in line with leading medical organizations.

In their announcements, California Gov. Gavin Newsom, Oregon Gov. Tina Kotek and Washington Gov. Bob Ferguson criticized recent Trump administration actions, including the firing of scientists and the upheaval at the CDC.

“When federal agencies abandon evidence-based recommendations in favor of ideology, we cannot continue down that same path,” Washington Secretary of Health Dennis Worsham said in a statement.

Worsham added that “public health at its core is about prevention — preventing illness, preventing the spread of disease, and preventing early, avoidable deaths.”

Last week, the U.S. Food and Drug Administration restricted access to updated COVID-19 shots. In June, Kennedy ousted all 17 members of the vaccine advisory committee at the CDC, replacing them with some members who are vaccine skeptics. Many states rely on the committee to form vaccination guidelines.

And in May, Kennedy rescinded recommendations for children and pregnant women to get vaccinated against COVID-19 — sidestepping the usual process for issuing official recommendations.

The three Western states said the “dismantling” of the CDC has created “a vacuum of clear, evidence-based vaccine guidance,” hampering health care providers, disrupting manufacturers’ production plans and creating uncertainty for families.

In 2020, at the start of the COVID-19 pandemic, the three states, along with Nevada, created a similar workgroup that emphasized the scientific rigor behind the Pfizer COVID-19 vaccine in an effort to boost confidence in the shot.

“President Donald Trump’s mass firing of CDC doctors and scientists — and his blatant politicization of the agency — is a direct assault on the health and safety of the American people,” the joint statement from the three governors’ offices said.

“The CDC has become a political tool that increasingly peddles ideology instead of science, ideology that will lead to severe health consequences. California, Oregon, and Washington will not allow the people of our states to be put at risk.”

School children, college students, and even nursing home residents would no longer have to be vaccinated against infectious diseases and viruses if Florida Surgeon General Joseph Ladapo and his boss, Gov. Ron DeSantis, have their way.

The DeSantis administration rolled out the proposed change on Wednesday and, if they’re successful, the state would be the first in the nation to completely eliminate vaccine requirements that many health experts credit with nearly eliminating some diseases.

“Your body is a gift from God. What you put into your body is because of your relationship with your body and your God,” said Ladapo, attacking the government mandates.

“It’s wrong, it’s immoral. They do not have the right to tell you what you put in your body. They don’t have the right to tell you what your kids have to put in [their] body. They do not have the right. Do not give it to them. Take it away from them. And we’re going to be starting that here in Florida.”

’Choose a side’

Neither Ladapo nor DeSantis discussed with legislative leadership their intent in the 2026 legislative session to push to eliminate vaccine mandates from the books before making the announcement.

The surgeon general praised the Legislature and went so far as saying he “loves our lawmakers.” But Ladapo issued an ultimatum.

“They’re going to have to make decisions, right? That’s the way that this becomes possible. So, people are going to have to make a decision. People are going to have to, have to choose a side. And I am telling you right now that you know the moral side is, it’s so simple.”

Patients would remain free to take shots if they like.

Democratic officials quickly blasted the announcement, deeming it a “reckless” decision that could lead to a drop in those immunized in the state. Florida has already seen its immunization rate for school-aged children tick down in recent years, although more than three-quarters of school children have received shots.

“This is ridiculous. Florida already has broad medical and religious exemptions for childhood vaccines, so any family that has a sincere opposition to vaccination can opt-out. Removing the mandate wholesale is dangerous, anti-science, and anti-child. Nobody wants to go back to the days of iron lungs,” Senate Democratic leader Sen. Lori Berman, from Boynton Beach, said in a statement.

“Republicans have gone from entertaining anti-science conspiracy theories to fully endorsing an anti-science health policy. As a member of the Senate Health Policy Committee, I’ll be doing everything in my power to protect our kids from these reckless attempts to harm them.”

Sen. Shevrin Jones, a Democrat from Miami Gardens, also criticized the announcement.

“Ending vaccine mandates poses a grave public health risk and will likely lead to a resurgence of preventable diseases. This reckless move jeopardizes the health and lives of countless Floridians — from children to seniors — especially those too young to be vaccinated or those with compromised immune systems. The DeSantis administration is actively undermining public health, making communities more vulnerable to outbreaks and increasing the burden on healthcare systems.”

Public Citizen’s Health Research Group Director Robert Steinbrook said ending all vaccine mandates is a “recipe for disaster” and goes in the wrong direction. He urged the Legislature to stand against the DeSantis administration.

“High immunization rates against dangerous infectious diseases such as measles and polio protect individuals as well as their communities. If this plan moves forward, Florida will terminate one of the most effective means of limiting the spread of infectious diseases and embolden U.S. Health and Human Services Secretary Robert F. Kennedy, Jr. to wreak even more havoc on vaccinations nationally. The Florida Legislature and state residents must vociferously reject these plans,” Steinbrook said in a prepared statement.

Current requirements

Florida law contains a number of immunization requirements for the young and the old.

Immunization for poliomyelitis, diphtheria, rubeola, rubella, pertussis, mumps, and tetanus are required for entry and attendance in Florida schools, childcare facilities, and family daycare homes. The state allows exemptions for valid medical reasons but also for religious and certain belief systems and, in some cases, allows personal exemptions for philosophical beliefs.

Florida law also requires school districts to develop and disseminate parent guides that include information about the importance of student health and available immunizations and vaccinations, including, but not limited to, recommended immunization schedules in accordance with federal recommendations.

The school guide must include detailed information regarding the causes, symptoms, and transmission of meningococcal disease and the availability, effectiveness, known contraindications, and appropriate age for the administration of any required or recommended vaccine against that infection.

The Florida Education Association issued a statement warning that changing the rules would endanger students and faculty.

“When leaders talk about pulling back vaccines, they’re talking about disrupting student learning and making schools less safe. State leaders say they care about reducing chronic absenteeism and keeping kids in school — but reducing vaccinations does the opposite, putting our children’s health and education at risk,” the union said.

“We’re reviewing the potential impacts on public schools and our communities. But, make no mistake, FEA will continue to stand up for our students, our educators, and our public schools.”

College students who reside in on-campus housing must provide documentation of vaccinations against meningococcal meningitis and hepatitis B. Again, the law contains exemptions and students who refuse the vaccines are required to sign waivers.

Nursing homes are required to assess residents within five business days post admission of eligibility for pneumococcal vaccinations or revaccinations. If indicated, the resident must be be vaccinated or revaccinated within 60 days after admission, in accordance with the recommendations of the U.S. Centers for Disease Control and Prevention, subject to exemptions for medical contraindications and religious or personal beliefs.

Immunization may not be provided to a resident who provides documentation that he or she has been immunized. A resident may elect to receive the immunization from his or her personal physician and, if so, the resident needs to provide proof of the immunization to the facility. The agency may adopt and enforce any rules necessary to comply.

2025 efforts fall short

The 2026 legislative session begins in January, which is when the DeSantis administration will work with the Legislature in hopes of accomplishing its goal. But the Department of Health will also revise rules for a handful of vaccines that are mandated in rule but not in statue.

A substantially scaled-back effort to address vaccine mandates fell short during the 2025 session.

The DOH this spring championed a broad bill (HB 1299) continuing a law initially passed in 2021 that banned businesses, government entities, and education institutions from denying people entry or service based on vaccination status or requiring people to wear masks. HB 1299 extended the ban for two years.

The bill expanded the Patient’s Bill of Rights and Responsibilities statutes to prohibit providers and facilities from denying admission, care, or services to a patient based solely on vaccination status.

Although the House agreed to the language, passing HB 1299 by a near-unanimous vote, state Sen. Gayle Harrell, a Republican from Stuart whose late husband was a physician, warned that the requirement would open doctors to increased liability. Sen. Jason Pizzo, a Hollywood lawmaker with no party affiliation, said the mandate to treat patients would have contradicted a law DeSantis championed that guarantees Florida physicians legal protections to not treat patients on the basis of their conscience.

The Senate deleted the language before passing the proposal and the House ultimately agreed to the Senate’s version.

Ladapo the lightning rod

Ladapo is a well known vaccine skeptic. He emphasized parents’ rights to send their kids to school unvaccinated in spring after a measles case in a Miami-Dade County high school. He altered a DOH COVID-19 vaccine study to exaggerate the risks of cardiac death for young men

His positions on vaccinations aren’t the only reason he’s become a public health lightning rod.

The DOH last month announced 21 cases of Campylobacter and E. coli infections tied to raw milk consumption in the central and northeast portions of the state, and said that seven people had been hospitalized. Six of the cases were reported in children under age 10. Nevertheless, Ladapo didn’t warn against consuming raw milk.

Two days later, Florida Agriculture Commissioner Wilton Simpson issued a statement encouraging residents to stick to pasteurized milk.

And in 2021, Ladapo made national headlines when he refused to don a mask during a meeting with state Sen. Tina Polsky, who was being treated for cancer and requested that he wear one. At the time, Ladapo was up for Senate confirmation.

Polsky, a Democrat from Boca Raton, lambasted Ladapo’s announcement Wednesday.

“Vaccines are crucial for our children because they protect them from deadly diseases and keep entire communities safe through herd immunity,” she said in a written statement.

Diseases, including polio, that once destroyed our children’s health and futures, will have the chance to return under this dangerous policy change. I voted against Dr. Ladapo’s confirmation in 2023 because he has a habit of misrepresenting science and making decisions that affect the health of Floridians. He remains determined to prioritize political dogma over smart health decisions.”

Florida Make America Healthy Again Commission

Ladapo’s announcement dovetails with DeSantis’ news that he has created a Florida Make America Healthy Again Commission that will recommend the integration of U.S. Department of Health and Human Services Secretary Robert F. Kennedy Jr.’s Make America Healthy Again effort. The Florida Commission will be co-chaired by  first lady Casey DeSantis and Lt. Gov. Jay Collins.

Meanwhile, at the end of August, the Food and Drug Administration approved updated vaccines for COVID-19. While previous versions of the vaccine were recommended to individuals 6 months of age and older, access to the FDA’s newly approved vaccines is limited to individuals 65 and older and individuals between the age of 5 and 64 with an underlying condition placing them at high risk for severe COVID-19.

Public health and access to lifesaving vaccines are on the line in a high-stakes leadership battle at the Centers for Disease Control and Prevention.

Health and Human Services Secretary Robert F. Kennedy Jr.’s push to fire CDC director Susan Monarez is more than an administrative shake-up. The firing marks a major offensive by Kennedy to seize control of the agency and impose an anti-vaccine, anti-science agenda that will have profound effects on the lives and health of all Americans, public health leaders say.

Kennedy wants to see the Pfizer and Moderna messenger RNA-based covid-19 vaccines pulled from the market, according to two people familiar with the planning who asked not to be identified because they’re not authorized to speak to the press. He’s also set his sights on restricting or halting access to some pediatric immunizations, some public health leaders say.

His actions have already reduced federal help to states, creating the potential for more infectious disease outbreaks and incidences of foodborne illness. Some public health leaders say they expect Kennedy will use the CDC to publicize health information that isn’t grounded in science.

“It’s crazy season,” said Richard Besser, former acting CDC director during the Obama administration. “People want information they can trust to make critical decisions about their health. Until now, we’ve been able to say look at the CDC. Unfortunately, we’re not able to do that anymore.”

HHS spokesperson Emily Hilliard disputed the criticism.

“Secretary Kennedy remains firmly committed to delivering on President Trump’s promise to Make America Healthy Again, dismantling the failed status quo that fueled a nationwide chronic disease epidemic and eroded public trust in our public health institutions,” Hilliard said in a statement.

White House spokesperson Kush Desai said Kennedy and Commissioner of Food and Drugs Marty Makary have reiterated that covid shots will remain available for Americans who need and want them.

“The Trump administration is restoring Gold Standard Science as the sole guiding principle of health decision-making,” Desai said in an email. “Only the Fake News could ignore these facts to continue pushing Democrat talking points and hysteria.”

Behind the ouster

The shake-up began last week, when Kennedy sought to fire Monarez, a microbiologist who’d just been confirmed by the Senate in July. She refused to leave the position, and her lawyers said Kennedy sought to oust her because she wouldn’t fire senior staff or follow unscientific directives. Four top career officials at the CDC resigned on Aug. 27 in protest.

Career staffers at the CDC and some public health groups had hoped President Donald Trump would intervene and put the brakes on Kennedy. Instead, the White House backed Kennedy, saying Monarez was fired.

Trump on Sept. 1 demanded that drug companies show that covid vaccines work, in a further sign he’s not set on defending the shots.

“I hope OPERATION WARP SPEED was as ‘BRILLIANT’ as many say it was. If not, we all want to know about it, and why???” Trump said on Truth Social.

Operation Warp Speed was the initiative that Trump himself announced in 2020 to accelerate the development of covid vaccines, including the Pfizer and Moderna shots. The vaccines have proved safe and effective in multiple clinical trials; a study published in JAMA Health Forum estimated that they saved about 2.5 million lives worldwide.

CDC staffers are worried the agency’s next director won’t fight for science, according to an employee who asked not to be identified for fear of professional retaliation.

Trump’s support for Monarez’s ouster was a watershed moment that signaled there are no checks on Kennedy and his agenda, public health advocates say. Leading congressional Democrats such as Senate Minority Leader Chuck Schumer called for Kennedy’s firing. Hundreds of HHS staffers have also implored Congress to intervene, saying Kennedy threatens science and public health. He is slated to testify Sept. 4 before the Senate Finance Committee.

Kennedy said in a message to CDC staff that his focus is on boosting the agency’s reputation and leadership. The Atlanta-based agency was already reeling after the Trump administration pushed out thousands of its staff and a gunman who reportedly believed the covid vaccine had caused him health problems fired hundreds of rounds at its campus last month, killing a police officer.

“The CDC must once again be the world’s leader in communicable disease prevention. Together, we will restore trust,” Kennedy wrote. “Together, we will rebuild this institution into what it was always meant to be: a guardian of America’s health and security.” He said his deputy, Jim O’Neill, would serve as acting CDC director.

Nine former CDC directors or acting directors who served under both Republicans and Democrats criticized Kennedy in the aftermath of the Monarez firing, saying in an op-ed in The New York Times that the impact on public health is “unacceptable, and it should alarm every American, regardless of political leanings.”

HHS spokesperson Hilliard took exception with this point, listing four covid vaccines that continue to get the nod for use.

However, the Food and Drug Administration last

week approved updated covid mRNA boosters only for people 65 or older and others at high risk of complications. The CDC has also stopped recommending the shots for healthy children and pregnant women. Previously, the shots had been advised for anyone 6 months or older.

As a result, many people who don’t meet the criteria but want the vaccine will have to get prescriptions or consult with their doctors. Insurance may not always cover the shots, which can run around $200. Major drugstores such as Walgreens and CVS have said the shots may not be available at all pharmacies and may require a prescription.

The American Academy of Pediatrics on Aug. 19 broke with the administration, recommending that all young children get the covid vaccine. Insurance still may not cover the cost in some cases and parents could face obstacles in getting the vaccines without a prescription.

Next move: The advisory committee

Kennedy and his team changed official covid vaccine recommendations even though there have been no new safety issues. A dose of the 2023-24 covid mRNA vaccine prevented significant illness and death across all age groups, according to a study published in August led by a University of Michigan researcher. The virus killed about 1,000 people a week in the U.S. in mid-January, and cases are rising again and expected to accelerate this winter.

Kennedy has handpicked a vaccine advisory committee for the CDC that is reviewing mRNA-based covid vaccines, which he falsely claimed in 2021 were “the deadliest vaccine ever made.” The covid vaccine review is being led by Retsef Levi, a professor of operations management at the Massachusetts Institute of Technology who has said without evidence that the shots cause serious harm, including death. If the committee recommends against them, Kennedy and the FDA could then begin the process of removing them from the market.

Taking mRNA-based covid shots off the market would leave consumers with fewer options for protection. Paxlovid, an antiviral medication that treats the infection in high-risk adults, would be available.

The CDC advisory committee reviewing the covid shots is also probing a long-debunked link between aluminum, used in many childhood immunizations such as those for hepatitis A and pneumonia, and autism or allergies.

The group’s findings are expected to support the erroneous link, some public health officials say. HHS could then require drugmakers to undertake costly reformulations of the shots or stop manufacturing them altogether.

“That would set up the elimination of all childhood vaccines,” Besser said.

The advisory group’s next meeting is set for Sept. 18, although Sen. Bill Cassidy (R-La.) has called for the meeting to be indefinitely delayed. Cassidy, a physician who chairs the Senate Health, Education, Labor and Pensions Committee, voted for Kennedy’s confirmation as HHS secretary after receiving assurances, he said, that the longtime vaccine opponent wouldn’t disrupt the U.S. vaccination system. Kennedy’s promises, Cassidy said, included that he wouldn’t change the CDC’s Advisory Committee on Immunization Practices.

Kennedy removed all of the panel’s members in June and replaced them with his own appointees, including anti-vaccine activists.

Kennedy’s move to put his stamp on the CDC means states that have long relied on the agency’s expertise and help in crises such as disease outbreaks will largely be left to fend for themselves, said Ashish Jha, who served as President Joe Biden’s covid response coordinator from 2022 to 2023.

“States are going to be left on their own,” Jha said. “States will struggle with the CDC incapable and dysfunctional. Our system is not designed for states to go it alone.”

The CDC typically plays a critical role by assisting states with disease surveillance, public health interventions, and outbreak response, especially when a crisis spills across state lines. An outbreak of measles this year led to more than 1,400 cases nationwide, and states including Texas, where the outbreak was identified, struggled to get help from the CDC.

A CDC program that has long tracked pathogens in food has already reduced the number of hazards it looks for from eight to two, which public health leaders say is making it harder to identify outbreaks. Staff overseeing a CDC program that tracks outdoor pollution that can exacerbate asthma also have been cut.

The agency runs a hotline that doctors around the country can call to get treatment and other types of advice. Under Kennedy’s watch, the CDC has had to pare assistance because of staffing reductions, said Wendy Armstrong, vice president at the Infectious Diseases Society of America.

“Lives are 100% at stake, no question about it,” Armstrong said. “That you can no longer trust the recommendations out of the CDC is just devastating. It’s appalling to think we can’t trust that information is science-based anymore.”

Kennedy wants to shake up CDC leadership because he sees the agency as the heart of corruption and resistance within the federal health bureaucracy, according to people familiar with his planning. Kennedy has said the agency suffers from malaise and bias.

Many public health leaders, however, view the CDC as under siege by an administration they say is corrupting science for its own ends. HHS staffers signed onto a letter that now has more than 6,800 signatures, saying Kennedy is “endangering the nation’s health by repeatedly spreading inaccurate health information.”

Kennedy has also been fending off mounting criticism of his response to the shooting at the CDC’s headquarters. He responded to the attack on social media, hours later, after first posting pictures of himself fly-fishing.

Some younger staffers are considering leaving and some workers feel like the shooting accelerated Kennedy’s overhaul of the agency, the CDC employee said.

With the battle for control of the CDC still raging, public health leaders are now looking to Congress to put the brakes on Kennedy. Some Republican lawmakers have called for a review of Kennedy’s actions.

“These high profile departures will require oversight by the HELP Committee,” Cassidy said Aug. 27 on the social platform X. Cassidy had backed Monarez to lead the agency.

WASHINGTON — Bipartisan leaders of a U.S. Senate committee dealing with health policy expressed alarm with the direction of the country’s top public health agencies after President Donald Trump fired the director of the Centers for Disease Control and Prevention and other high-level officials resigned. 

Louisiana Republican Sen. Bill Cassidy — chairman of the Health, Education, Labor and Pensions Committee — posted on social media late Wednesday that the “high profile departures will require oversight by the HELP Committee.”

Cassidy separately called on the Advisory Committee on Immunization Practices to indefinitely postpone its September meeting.

“Serious allegations have been made about the meeting agenda, membership, and lack of scientific process being followed for the now announced September ACIP meeting,” Cassidy wrote in a statement. “These decisions directly impact children’s health and the meeting should not occur until significant oversight has been conducted. If the meeting proceeds, any recommendations made should be rejected as lacking legitimacy given the seriousness of the allegations and the current turmoil in CDC leadership.”

Vermont independent Sen. Bernie Sanders, ranking member on the committee, called for a bipartisan investigation into the reasons Trump fired Susan Monarez as CDC director less than a month after she received Senate confirmation.

Sanders said that Health and Human Services Director Robert F. Kennedy Jr., Monarez and the handful of high-ranking CDC officials who resigned this week should be able to testify publicly about what’s happening inside the agency. 

“We need leaders at the CDC and HHS who are committed to improving public health and have the courage to stand up for science, not officials who have a history of spreading bogus conspiracy theories and disinformation,” Sanders wrote.

White House press secretary Karoline Leavitt said during a briefing that Trump had every right to fire Monarez and that he expects to pick a new nominee “very soon.”

“Her lawyers’ statement made it abundantly clear themselves that she was not aligned with the president’s mission to make America healthy again,” Leavitt said. “The secretary asked her to resign. She said she would and then she said she wouldn’t. So the president fired her, which he has every right to do.” 

Kennedy is scheduled to testify before the Senate Finance Committee next week, that panel’s chairman, Idaho Republican Mike Crapo, announced Thursday.

Kennedy “has placed addressing the underlying causes of chronic diseases at the forefront of this Administration’s health care agenda,” Crapo wrote on X. “I look forward to learning more about @HHSGov’s Make America Healthy Again actions to date and plans moving forward.”

Cassidy key vote for RFK

Cassidy was an essential vote to confirm Kennedy as director of HHS, which oversees the CDC, though he expressed concerns throughout that process that Kennedy’s past statements about vaccines weren’t rooted in reputable medical research.

Cassidy said during a floor speech in February after voting to advance Kennedy’s nomination that Kennedy assured him he will protect “the public health benefit of vaccination.” 

“If Mr. Kennedy is confirmed, I will use my authority of the Senate committee with oversight of HHS to rebuff any attempt to remove the public’s access to life-saving vaccines without ironclad causational scientific evidence that can be accepted and defended before the mainstream scientific community and before Congress,” Cassidy said at the time. “I will watch carefully for any effort to wrongly sow public fear about vaccines between confusing references of coincidence and anecdote.”

President Donald Trump’s administrations have been notorious for an array of “alternative facts” — ranging from the relatively minor (the size of inaugural crowds) to threats to U.S. democracy, such as who really won the 2020 election.

And over the past six months, the stakes have been life or death: Trump’s health officials have been endorsing alternative facts in science to impose policies that contradict modern medical knowledge.

It is an undeniable fact — true science — that vaccines have been miraculous in preventing terrible diseases from polio to tetanus to measles. Numerous studies have shown they do not cause autism. That is accepted by the scientific community.

Yet Secretary of Health and Human Services Robert F. Kennedy Jr., who has no medical background or scientific training, doesn’t believe all that. The consequences of such misinformation have already been deadly.

For decades, the vast majority Americans willingly got their shots — even if a significant slice of parents had misgivings. A 2015 survey found that 25% of parents believed that the measles, mumps, and rubella (MMR) vaccine could cause autism. (A 1998 study that suggested the connection has been thoroughly discredited.) Despite that concern, just 2% of children entering kindergarten were exempted from vaccinations for religious or philosophical objections. Kids got their shots.

But more recently, poor government science communication and online purveyors of misinformation have tilled the soil for alternative facts to grow like weeds. In the 2024-25 school year, rates of full vaccination for those entering kindergarten dropped to just over 92%. In more than a dozen states, the rate was under 90%, and in Idaho it was under 80%. And now we have a stream of measles cases, more than 1,300 from a disease declared extinct in the U.S. a quarter-century ago.

It’s easy to see how both push and pull factors led to the acceptance of bad science on vaccines.

The number of recommended vaccines has ballooned this century, overwhelming patients and parents. That is, in large part, because the clinical science of vaccinology has boomed (that’s good). And in part because vaccines, which historically sold for pennies, now often sell for hundreds of dollars, becoming a source of big profits for drugmakers.

In 1986, a typical child was recommended to receive 11 vaccine doses — seven injections and four oral. Today, that number has risen to between 50 and 54 doses by age 18.

The Advisory Committee on Immunization Practices, which renders judgments on vaccines, makes a scientific risk-benefit assessment: that the harm of getting the disease is greater than the risk of side effects. That does not mean that all vaccines are equally effective, and health officials have done a lackluster job of fostering public understanding of that fact.

Older vaccines — think polio and measles — are essentially 100% effective; diseases that parents dreaded were wiped off the map. Many newer vaccines, though recommended and useful (and often heavily advertised), don’t carry the same emotional or medical punch.

Parents of the current generation haven’t experienced how sick a child could be with measles or whooping cough, also called pertussis. Mothers didn’t really worry about hepatitis B, a virus generally transmitted through sex or intravenous drug use, infecting their child.

That lack of understanding spawned skeptics. For example, since 2010, the vaccine for influenza, which had been around for decades, has been recommended annually for all Americans at least 6 months old. In the 2024-25 season, the rate of flu vaccination was only between 36% and 54% in adults; in other years, it has been lower than that. “I got the flu vaccine, and I still got the flu” has been a common refrain of skeptics.

“Pre-covid, there were people who took everything but flu,” said Rupali Limaye, an associate professor at Johns Hopkins University’s Bloomberg School of Public Health, who studies vaccine demand and acceptance. “Then it became everything but covid. Now it’s everything — including MMR and polio.”

Even as the first Trump administration’s Operation Warp Speed helped develop covid vaccines, conservative media outlets created doubts that the shots were needed: doubts that mRNA technology had been sufficiently tested; doubts that covid-19 was bad enough to merit a shot; concerns that the vaccines could cause infertility or autism.

Trump did little to correct these dangerous misperceptions and got booed by supporters when he said that he’d been vaccinated. Once vaccine mandates came into play, Trump strongly opposed them, reframing belief in the vaccine as a question of personal liberty. And if the government couldn’t mandate the covid shot for school, it followed that officials shouldn’t — couldn’t — mandate others.

Thus 100 years of research proving the virtues of vaccination got dropped into a stew of alternative facts. You were either pro- or anti-vaccine, and that signaled your politics. Suddenly, the anti-vax crowd was not a small fringe of liberal parents, but a much larger group of conservative stalwarts who believed that being forced to vaccinate their kids to enter school violated their individual rights.

Even within the Trump administration, there have been some who (at least partly) decried the trend. While Marty Makary, the Food and Drug Administration commissioner, defended Kennedy’s decision to roll back the recommendation that all Americans get annual covid boosters — saying the benefits were unproven — he noted it should not be a signal to stop taking other shots.

As “public trust in vaccination in general has declined,” he wrote, the reluctance to vaccinate had harmed “vital immunization programs such as that for measles–mumps–rubella (MMR) vaccination, which has been clearly established as safe and highly effective.”

Nonetheless, Makary’s boss, Kennedy, continued to promote bad science about vaccines broadly, even as he sometimes grudgingly acknowledged their utility in cases like a measles outbreak. He has funded new research on the already disproven link between MMR shots and autism. He has halted $500 million in grants for developing vaccines using mRNA technology, the novel production method used for the first covid vaccines and a technique scientists believe holds great promise for preventing deaths from other infectious diseases.

In my 10 years practicing as a physician, I never saw a case of measles. Now there are cases in 40 states. More than 150 people have been hospitalized, and three, all unvaccinated, have died.

Alternative facts have formed what David Scales, a physician and sociologist at Weill Cornell Medical College who studies misinformation, calls “an unhealthy information system.” It is an alternative scientific universe in which too many Americans live. And some die.

Reading Time: 4 minutes

Before the 1960s, hundreds of thousands of Americans faced measles infections each year. The advent of vaccination eliminated the disease in the United States by 2000. But outbreaks have returned to some U.S. communities as trust in vaccines wanes in many communities.

More than 1,300 measles cases have been confirmed this year across 41 states, the latest being Wisconsin. That’s after the state Department of Health Services on Saturday announced it confirmed nine measles infections in Oconto County — the first in Wisconsin this year. 

Each Oconto County infection involved exposure to a “common source during out-of-state travel,” the state health department said in a statement. 

“DHS, in coordination with the Oconto County Public Health, is working to identify and notify people who may have been exposed to the measles virus,” the statement said. “At this time no public points of exposure have been identified and the risk to the community remains low.”  

What should Wisconsin families know about measles? 

Wisconsin Watch spoke with two University of Wisconsin-Madison experts: Dr. Jim Conway, a professor in the Divisions of Infectious Diseases and Global Pediatrics; and Malia Jones, an assistant professor in the Department of Community and Environmental Health.

We gathered additional information from officials at multiple rural public health departments across Wisconsin and reports from the U.S. Centers for Disease Control and Prevention.

Below are some takeaways. 

When and where am I most susceptible to measles?

That depends on individual health and vaccination status. Very young people (especially infants too young to be vaccinated), older adults and people with compromised immune systems face higher risks for contracting measles and developing severe complications.

Measles tends to spread more easily in crowded urban environments and during travel. However, it can spread anywhere, as evidenced by recent rural outbreaks, including those in Texas, where hundreds of infections have been confirmed and two school children have died. All it really takes is exposure to an infected person. Measles is one of the most highly contagious known diseases. It can remain infectious in the air or on surfaces even after an infected person leaves the area.

To put it in perspective, measles is often reported to have an R nought value — the number used to describe contagiousness — between 12 and 18. That means if one person with measles walked into a room of vulnerable people, odds are they would infect 12 to 18 others in the room. 

What should I do if I start having measles symptoms?

Measles often starts with general cold-like symptoms such as fever, cough, runny nose and watery eyes, making it hard to immediately recognize. The rash typically appears a few days after infection — and after a contagious person may have exposed others. 

If you think you might have measles or have been exposed to it, contact your local health department or healthcare provider immediately — especially if you’re unvaccinated or traveled to an area where cases were reported.  Suspected cases can be reported to local health departments even before confirmation, allowing officials to respond more quickly. Experts recommend staying home while waiting for test results to avoid spreading the virus.

What are the risks of measles?

While some think of measles as a mild childhood illness that everyone used to get, it can be dangerous. The disease can lead to a range of complications, from ear infections and diarrhea to more severe pneumonia or brain-swelling encephalitis. Such brain inflammation can affect multiple parts of the body and even cause permanent damage, especially to the brain and hearing. 

Meanwhile, a  rare but fatal long-term brain disease called subacute sclerosing panencephalitis can develop years after the initial infection. 

Some people infected by measles may experience neurological issues or nerve damage later in life.

One lesser-known risk factor: Measles can disrupt the part of the immune system that remembers previous infections, a phenomenon known as immunity amnesia. That leaves people more vulnerable to future viruses for two to three years after a measles infection.

In higher-income countries measles kills 1 to 3 of every 1,000 people infected, 10% to 20% of infections requiring hospitalization — often due to pneumonia, dehydration or severe diarrhea. Encephalitis occurs in about 1 in 1,000 cases, and pneumonia occurs in about 5% of infections. Children who are malnourished or have limited access to medical care face significantly greater risks. 

U.S. health officials have confirmed three measles-related deaths this year. 

What if I’m unsure whether I’ve had measles or the vaccine?

If you were born before 1957, you’re generally considered immune to measles because the virus was so widespread during the pre-vaccine era. Many adults born in the 1960s and 1970s may assume they’re protected when, in fact, they were never fully vaccinated, or even vaccinated at all. A second dose of the measles, mumps and rubella (MMR) vaccine wasn’t added to routine childhood immunization schedules until 1989, so many adults missed one or both recommended doses. 

The bottom-line is if there’s any uncertainty around your vaccination status, it’s safe to get vaccinated again. There’s no harm in receiving an additional dose of the MMR vaccine. In fact, an extra dose is both safe and more practical — quicker and more cost-effective than getting a blood test to check your immunity.

“More is better,” Conway said. “This is not one of the vaccines that has particularly tough side effects.”

Staying up to date not only protects you from serious illness but also helps safeguard others in your community who may be more vulnerable to complications from measles.

What can I do to protect myself and others?

Vaccination is your best defense. The MMR vaccine is the most effective way to protect yourself and those around you from measles. Make sure you’ve received both recommended doses, and stay informed about outbreaks in your community, especially if you’re traveling or belong to a vulnerable group.

Measles has made it to Wisconsin. Here’s what to know about the virus. is a post from Wisconsin Watch, a non-profit investigative news site covering Wisconsin since 2009. Please consider making a contribution to support our journalism.

A pair of Wisconsin Republicans want to increase awareness of the state’s vaccine exemptions by requiring waiver forms be given to parents with the health forms they receive from schools and child care center providers. 

Coauthors of the bill Rep. Lindee Brill (R-Sheboygan Falls) and Sen. Rachael Cabral-Guevara (R-Appleton) said in a cosponsorship memo that there is a “lack of transparency” around the exemptions that “can create confusion and unnecessary barriers for parents” and “increase administrative burden on schools when immunization documentation is incomplete or delayed.” 

Wisconsin law requires children in elementary, middle, junior or senior high school, a child care center, or a nursery school to get vaccinated for various diseases based on their grade or age. The vaccine and booster schedule covers mumps, measles, rubella, diphtheria, pertussis, poliomyelitis and tetanus. 

Wisconsin allows parents to get the requirement waived if they submit a written statement objecting for reasons including health, religious or personal conviction. 

Lawmakers noted that the bill would not change current requirements for vaccines. The bill would require schools, child care centers and nursery schools to create a process to present a vaccine waiver form with each health-related form it requires before a student can be enrolled.

“Many parents are unaware of this right or are unclear about how to obtain that waiver and feel pressured to make medical decisions for their children that they otherwise would not have,” Brill said in a statement. “This bill ensures that schools make parents aware of the rights already afforded them by Wisconsin law and include information about the waiver from the vaccine requirement and a procedure for presenting it in any required pre-enrollment health-related forms.”

The proposal comes as Wisconsin’s vaccination rates have not caught up with pre-pandemic levels. According to a 2024 U.S. Centers for Disease Control report, Wisconsin is falling behind other states in childhood immunizations for illnesses including polio, pertussis, diphtheria and tetanus, and measles, mumps and rubella. 

The decline in vaccine rates is partially to blame for diseases, including measles and pertussis, increasing across the country, according to health officials. 

According to the Wisconsin Department of Health Services, 86.4% of students met the minimum immunization requirements during the 2024-25 school year — a 2.8 percentage-point decrease from the prior year. The agency also reports that 6.7% of students had a waiver for one or more immunizations, representing a 0.6 percentage-point increase from last year, though the number of students waiving all vaccines fell to 1.3%. 

Amid falling rates, DHS officials have ramped up efforts to encourage vaccinations to help improve effectiveness. 

Wisconsin has one of the lowest measles vaccination rates in the country, with only Alaska falling below it. One dose of the MMR vaccine, which fights measles, provides approximately 93% protection, while two doses are about 97% effective.

As measles vaccine rates have fallen, cases of the highly contagious disease have hit the highest level in 33 years, according to the CDC with 1,288 cases this year. More than 150 people have been hospitalized from measles, and three people have died this year. No cases have been reported in Wisconsin so far, but its neighboring states, including Illinois and Minnesota, have had cases.

The lawmakers’ efforts to increase awareness of vaccine exceptions comes amid a national wave of skepticism to vaccination, including from U.S. Health Secretary Robert F. Kennedy Jr., who is a leading and prominent vaccine skeptic and was appointed by President Donald Trump this year. 

Brill thanked Kennedy for his work on his “Make America Health Again” agenda in her statement about the bill.

Cabral-Guevara, a board certified family nurse practitioner, has supported legislation that would loosen vaccine requirements before including a 2024 bill that would have allowed immunization exemptions at higher education institutions without documentation. 

The bill passed the Senate and Assembly, but was vetoed by Gov. Tony Evers, who said in a veto message that he objected to “the Wisconsin State Legislature’s efforts to micromanage decisions to respond to public health incidents and restrict existing tools available to higher education institutions to keep students, faculty, staff safe and healthy on their campuses.”

WASHINGTON — President Donald Trump’s candidate to lead the Centers for Disease Control and Prevention advanced out of a Senate committee Wednesday following a party-line vote, moving her one step closer to confirmation.

Susan Monarez’s nomination now goes to the floor, where she will likely secure the backing needed to officially take on the role of CDC director after garnering support from Republicans across the political spectrum during the committee’s 12-11 vote.

Senate Majority Leader John Thune, R-S.D., will be in charge of scheduling that vote, though if it isn’t held during the next few weeks, Monarez will have to wait until after the chamber’s August recess.

Chairman Bill Cassidy, R-La., said during the Health, Education, Labor and Pensions Committee’s markup he believes Monarez is a strong candidate for CDC director and that he hopes she will help get the nation’s ongoing measles outbreak under control.

“The United States needs a CDC director who makes decisions rooted in science, a leader who will reform the agency and work to restore public trust in health institutions,” Cassidy said. “With decades of proven experience as a public health official, Dr. Monarez is ready to take on this challenge.”

Sanders criticizes Monarez on vaccine safety

Every Republican senator on the committee, including Maine’s Susan Collins and Alaska’s Lisa Murkowski, voted to advance Monarez’s nomination.

Vermont independent Sen. Bernie Sanders, ranking member on the panel, opposed Monarez’s advancement along with the Democrats on the committee.

Sanders argued that during Monarez’s time as acting director of the CDC, she didn’t do enough to counter Secretary of Health and Human Services Robert F. Kennedy Jr., especially on the safety of vaccines. 

“Today, the United States is reporting the highest number of measles cases in 33 years,” Sanders said. “In my view, we need a CDC director who will defend science, protect public health and repudiate Secretary Kennedy’s dangerous conspiracy theories about safe and effective vaccines that have saved, over the years, millions of lives.”

Second CDC choice from Trump

Monarez testified before the Health, Education, Labor and Pensions Committee in June, a standard part of the confirmation process.

Trump originally selected former Florida U.S. Rep. Dave Weldon to run the Atlanta-based CDC shortly after he secured election to the Oval Office in November. But the White House pulled Weldon’s nomination in March, after it appeared he couldn’t secure the votes needed for confirmation.

Later that month, Trump announced his plans to nominate Monarez in a social media post.

“Dr. Monarez brings decades of experience championing Innovation, Transparency, and strong Public Health Systems,” Trump wrote. “She has a Ph.D. from the University of Wisconsin, and PostDoctoral training in Microbiology and Immunology at Stanford University School of Medicine.

“As an incredible mother and dedicated public servant, Dr. Monarez understands the importance of protecting our children, our communities, and our future. Americans have lost confidence in the CDC due to political bias and disastrous mismanagement. Dr. Monarez will work closely with our GREAT Secretary of Health and Human Services, Robert Kennedy Jr. Together, they will prioritize Accountability, High Standards, and Disease Prevention to finally address the Chronic Disease Epidemic and, MAKE AMERICA HEALTHY AGAIN!”

As we continue to report on Wisconsin’s readiness for potential measles outbreaks, we have spoken to several people who have shared their memories of having measles before a vaccines were widely available. We’d love to hear from more of you. 

Before the 1960s, hundreds of thousands of Americans faced measles infections each year. The advent of vaccination eliminated the disease in the United States by 2000. But outbreaks have returned to some U.S. communities as trust in vaccines wanes in many communities.

We’re following whether measles will return to Wisconsin, which has some of the nation’s lowest vaccination rates for children.

If you have a story to share, whether it’s your own experience with measles or your observations of what it was like at the time, please take a moment to fill out this short form. Your submissions will shape the direction of our reporting and will not be shared publicly. But we may follow up with those who indicate they are comfortable with us doing so. 

Thanks to those who have already shared their perspectives and questions.
