WASHINGTON — A majority of Americans disapprove of Health and Human Services Secretary Robert F. Kennedy Jr.’s job performance and the federal government’s evolving vaccine policy, according to a poll released Thursday by the nonpartisan health organization KFF.

In addition, the vast majority of those surveyed have heard the unproven claims made by President Donald Trump, Kennedy and others in late September that taking acetaminophen, also known as Tylenol, during pregnancy could be one possible environmental factor in a child later being diagnosed with autism.

A total of 77% of the people KFF polled said they knew of the statements, though whether people believe the claims, which have yet to be established by the medical community, varied.

Only 4% of those surveyed said it is “definitely true” that taking Tylenol during pregnancy increases the risk of the child developing autism, and 35% said the claim is “definitely false.” Thirty percent said it is “probably true” and 30% said it is “probably false.”

Combined, 65% said it’s either probably or definitely false to say that taking acetaminophen during pregnancy increases the chance of a child developing autism, a complex disorder that experts believe is the result of both genetic and environmental factors.

When broken down by political party, 86% of Democrats, 67% of independents and 43% of Republicans said the claims were either probably or definitely false.

The survey shows 59% somewhat or strongly disapprove of how Kennedy is handling his new role at the top of the country’s public health infrastructure.

The level of support changes considerably depending on political party affiliation, with 86% of Democrats, 64% of independents and 26% of Republicans disapproving.

A slightly higher number, 62%, either somewhat or strongly disapprove of the United States’ vaccine policy.A similar trend emerged when those polled were broken up by political parties. Eighty-eight percent of Democrats, 67% of independents and 31% of Republicans somewhat or strongly disapproved of vaccine policy.

The survey shows a declining share of Americans have faith in the Centers for Disease Control and Prevention to provide trusted information about vaccines, compared with previous KFF polls in September 2023 and earlier this year.

A total of 63% of respondents two years ago trusted the CDC on vaccines, but that has declined to 50%.

Democrats’ faith in the CDC’s vaccine recommendations has dropped from 88% two years ago to 64%, independents have gone from 61% to 47% and Republicans have remained relatively steady, only going from 40% to 39%.

Across political parties, a person’s own doctor as well as the American Academy of Pediatrics and the American Medical Association remain broadly trusted for vaccine information.Eighty-three percent said they trust their doctor or health care provider, 69% believed information from the American Academy of Pediatrics and 64% had faith in the AMA.

The poll of 1,334 adults took place from Sept. 23 to Sept. 29 and had a margin of error of plus or minus 3 percentage points for the full survey. Questions broken down by a person’s political ideology had a margin of error of plus or minus 6 percentage points.

WASHINGTON — The vast majority of Americans, including Republicans and those who identify as strong supporters of President Donald Trump, want Congress to renew the enhanced tax credits for people who buy their health insurance from the Affordable Care Act Marketplace, according to a poll released Friday. 

More than 78% of people surveyed by the nonpartisan health organization KFF in late September said they want lawmakers to keep the enhanced credits. Their extension has become a major linchpin in debate about the government shutdown. 

When broken down by political party, 92% of Democrats, 82% of independents and 59% of Republicans supported renewing the credits.

Within the Republican Party, 57% of people who identified as supporting Trump’s Make America Great Again policies and 70% of GOP voters who identified as non-MAGA supporters want to see the tax credits extended, according to the poll.  

Spending bill held up over tax credit debate

The ACA tax credit expansion was created by Democrats in a coronavirus relief bill approved during the Biden administration and set to expire at the end of the year. 

Democrats have repeatedly called on Republicans to negotiate an extension of the enhanced tax credits and have held up a stopgap spending bill to force those talks to happen now, rather than later in the year. 

Speaker Mike Johnson, R-La., said Thursday the discussion should happen during the next few months and that GOP lawmakers will press for “major reform.” 

“That’s not a simple issue. That’s going to take weeks to deliberate and discuss and debate, but that’s the beauty of the process. We have three months to do that. That is not an issue for today,” Johnson said. “Today the only issue is whether they’re going to vote to keep the government operating for the people.”

Democrats strongly disagree, saying a bipartisan accord must be struck before the open enrollment period for ACA plans begins on Nov. 1, when consumers will see large cost increases for next year. 

“We can’t accept an empty promise, which is, ‘Oh, we’ll deal with this later,’” Sen. Patty Murray, D-Wash., said on a call with reporters Thursday. “The fact is that this crisis is in front of us now. People are getting this month their premium increases if the Senate does not act.”

Murray said she finds it “ironic” that Republican leaders are saying they’ll negotiate with Democrats on health care once the government reopens after they “refused to negotiate with us during that entire time when government was open.”

The House voted mostly along party lines in mid-September to approve a seven-week stopgap spending bill that has since stalled in the Senate, leading to the shutdown.

The upper chamber, where major legislation needs at least 60 votes to advance, is set to vote again Friday to try to advance Republicans’ short-term government funding bill, though it’s unlikely to move forward amid the stalemate.  

Many of those polled knew little about shutdown debate 

The KFF poll looked at public knowledge and understanding about the enhanced tax credits for ACA Marketplace health insurance plans, finding 61% of respondents knew nothing or only a little about the issue. 

Another 32% of those surveyed said they know some about the policy debate and 7% said they know a lot. 

The poll of 1,334 adults took place Sept. 23 to Sept. 29 and has a margin of error of plus or minus 3 percentage points for a full survey. Each political affiliation question has a margin of error of plus or minus 6 percentage points.

The government shutdown began on Oct. 1, just after the poll wrapped. 

Concern about the ramifications of letting the enhanced tax credits expire fluctuated when KFF asked the question in different ways, though those who said they were “very concerned” never dipped below a majority. 

Fifty-six percent were very concerned and 30% were somewhat concerned when told “health insurance would be unaffordable for many people who buy their own coverage” if the enhanced tax credits weren’t extended. 

The number of people who would be very or somewhat concerned was high among Republicans, 78%, and MAGA supporters, 76%. 

Respondents who were very concerned rose to 60% when told “about 4 million people will lose their health insurance coverage” if they do not keep receiving the enhanced credits. An additional 26% said they were somewhat concerned and 10% said they were not too concerned, with the rest of those polled saying they were not concerned at all. 

When broken down by political party, the number of people very or somewhat concerned remained high, with 76% of Republicans and 73% of MAGA supporters citing worry. 

Small business staff, self-employed people

Fifty-one percent of those polled said they were very concerned when told “millions of people who work at small businesses or who are self-employed would be directly impacted as many of them rely on the ACA marketplace.”

Another 33% said they were somewhat concerned, 11% said they were not too concerned and the remainder said they were not concerned at all. 

Seventy-five percent of Republicans and 72% of MAGA supporters responded they would be very or somewhat concerned when asked that question. 

The poll showed that Congress extending the enhanced tax credits as they exist now comes with some trepidation about the price tag. 

When asked how concerned people would be if they heard “it would require significant federal spending that would be largely paid for by taxpayers,” 27% said they would be very concerned, 36% somewhat concerned, 28% not too concerned and 8% not at all concerned. 

Forty-one percent of Republicans said they would be very concerned, with another 41% responding they would be somewhat concerned. An additional 15% said they would be not too concerned with the rest saying they were not concerned at all.
