Wisconsin’s rate for vaccinating 5- and 6-year-olds against measles, mumps and rubella (MMR) has continued to slide since the COVID-19 pandemic began, with 74.1% of such children receiving two doses of the shot in 2024 — down from 79.3% in 2019. 

Nearly every Wisconsin county last year vaccinated a lower share of kindergarten-aged children for MMR than before the pandemic. Menominee County, home to the Menominee Indian tribe of Wisconsin, was the lone exception, according to Wisconsin Department of Health Services data. 

After dipping from nearly 80.7% in 2019 to as low as 74.7% during the height of the pandemic, Menominee County’s MMR vaccination rate for kindergartners grew to nearly 83.6% in 2024, the state’s highest rate. 

That success was due to local health officials “being proactive” and conducting outreach that included “looking up kids that were behind, reaching out to parents and encouraging them to bring them in,” said Faye Dodge, director of community health nursing services at the Menominee Tribal Clinic.

Vaccination rates matter because measles is highly contagious and potentially dangerous.

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.

The U.S. Centers for Disease Control though June 19 confirmed more than 1,200 measles cases this year in 36 states, including every state bordering Wisconsin. About 12% of cases sent patients to the hospital. Three people have died.  

Wisconsin, which has some of the nation’s lowest vaccination rates for children, has been lucky to have dodged cases so far, said Margaret Hennessy, a pediatrician and member of the Wisconsin Council on Immunization Practices.

Wisconsin’s risk of outbreaks will grow as families with children travel over the summer.

“They’re going to be traveling all over the country,” Hennessy said. “Realistically, it’s likely a matter of time for somebody who’s not vaccinated or doesn’t have immunity to get the disease.”

Wisconsin Watch analyzed statewide vaccination data for 5- and 6-year-olds in the state, conducted other research and spoke to public health officials.

Here are some takeaways:

  • The COVID-19 pandemic disrupted local vaccination programs, leaving children behind in their vaccination schedules. Understaffed, under-resourced counties have struggled to catch up. 
  • Creating relationships with trusted community members and reducing access barriers is the most effective way to inoculate more children against contagious diseases like measles, public health officials say. 
  • No Wisconsin county comes close to reaching the vaccination rate of 95% that is considered the benchmark for herd immunity protection. That was true in 2024 and before the pandemic. 
  • Just three counties — Manitowoc, Marathon and Kewaunee — fully vaccinated at least 80% of kindergarten-aged children in every year from 2019 to 2024. 
  • While vaccination rates are lagging from pre-pandemic levels in most counties, 28 of Wisconsin’s 72 counties reported vaccination gains between 2023 and 2024 — four more than the previous year. Still, the majority of counties saw declines.

Vaccination rates are plunging in Clark County, which consistently ranks lowest statewide for vaccinating 5- and 6-year-olds against measles. Just 42.9% of those children received both MMR doses in 2024, down from 57.9% in 2019. 

Brittany Mews, Clark County’s health officer and director, cites a range of challenges in her sprawling county. Those include distances between few clinics in communities with no public transportation, low levels of health insurance access and diverse populations who face language barriers — and may adhere to cultural norms that prioritize traditional remedies over Western medicine.

But the county has found some success in partners ranging from school districts and child care centers to faith communities, Mews said. The health department has asked schools to notify parents when their children need vaccines, for instance, and positive feedback prompted the scheduling of multiple vaccine clinics at the schools and community churches.

Community partnerships in familiar places make people feel more comfortable — particularly in the county’s diverse communities, including those with language and cultural differences. 

Clark County is also working to increase vaccine access by partnering with neighboring health departments to offer vaccination clinics six times a year at a church food pantry, creating a “one-stop-shop” system, Mews said.   

Forging personal connections can grow trust and spread accurate information at a time when disinformation is running rampant online, Hennessy said. Hearing about positive vaccination experiences from a parent, neighbor or other trusted source can hold more weight than information a physician shares. 

“It’s unfortunate that we all can’t be everywhere all the time to fill that,” Hennessy said.

Heather Feest, a Manitowoc County public health nurse manager, said patience and understanding of concerns are also key to increased vaccinations.

“We’re not trying to persuade one way or another, it’s giving that information and answering questions — and allowing them to get factual information and have a conversation without judging,” Feest said. “It’s harder now than what it used to be.”

DataWatch: Trump’s tariffs and Wisconsin’s economy

Reading Time: 3 minutes

President Donald Trump’s fluctuating tariff policies have kept the world guessing.

Uncertainty about what’s next — and how U.S. companies will absorb new costs —  has stirred anxiety among investors, business owners and consumers. 

“That whipsawing back and forth, that creates a tremendous amount of uncertainty,” said  Steven Deller, a University of Wisconsin-Madison professor who researches the state’s agricultural and manufacturing economy. “And one thing that the economy hates is uncertainty.” 

What does it all mean for Wisconsin? Fast-shifting policies make that difficult to definitely say. But Wisconsin Watch spoke with experts and examined economic numbers to provide some context. 

First, what are tariffs and why is Trump issuing them? 

Tariffs are a federal tax American importers pay when goods arrive from other countries. 

The U.S. previously forged free trade agreements with 20 countries that limited tariffs in trade. Trump’s tariffs have blown up the status quo and prompted retaliation that has harmed some domestic producers and further rattled the global economy. 

The Trump administration has cited several justifications for his policies, some of them conflicting. It says tariffs will boost manufacturing by encouraging Americans to buy domestic goods, reduce U.S. trade deficits and pressure countries to cut deals on other issues — like curbing the fentanyl trade and illegal immigration. 

To what do Trump’s tariffs apply?

First Trump added “national emergency” tariffs ranging from 10% to 25% on imports from China, Canada and Mexico. After adjusting those tariffs several times, he announced on April 2 a baseline 10% tariff on goods from all countries that export to the U.S., along with higher “reciprocal” tariffs on countries with which the U.S. has trade deficits — a move that set the stock market plunging. Trump paused most reciprocal tariffs days later. 

As it stands, most Chinese imports face tariffs of 145%, while Canada and Mexico face 25% tariffs, along with 10% for most everyone else. 

Trump has exempted some goods from reciprocal tariffs, including copper, pharmaceuticals, lumber and electronics such as smartphones and laptops. However, Trump administration investigations of the national security and economic effects of importing items he exempted could result in additional tariffs. The White House has placed a 25% tariff on steel and aluminum imports.

How is this playing in Wisconsin? 

Wisconsin’s large manufacturing and agricultural sectors make its economy strong, said Missy Hughes, secretary and CEO of the Wisconsin Economic Development Corp. But business leaders she works with are increasingly hesitating to make big investments.

“It’s frustrating because our businesses were doing really well, and the Wisconsin economy is strong and has been strong for the last two years,” she said.

How much does Wisconsin import? 

Wisconsin imported more than $38 billion in goods last year, about half from countries facing the highest Trump tariffs: China, Canada and Mexico.

Machinery and electronic products made up about one-third of Wisconsin’s total import value last year. Pharmaceutical products, some of which Trump has since spared from tariffs, made up 12%.

Who bears the cost of tariffs?  

Importers pay tariffs to Customs and Border Protection when goods enter the country. The companies may absorb those costs or pass them to consumers by hiking prices — a common scenario.

Deller calls tariffs a regressive tax because they most affect people with lower income.

“They tend to spend their money more on goods than services,” he said. “They’re more likely to shop at a Walmart or a Dollar General-type store, and a lot of the goods that are sold in those kinds of stores come from international markets.”

How might tariffs affect Wisconsin manufacturers? 

“U.S tariffs might benefit domestic manufacturers if they serve as a negotiating tool to encourage other countries to lower their own tariffs or other barriers to trade,” according to a recent Wisconsin Policy Forum report. “They might also insulate Wisconsin manufacturers from international competition at home.” 

But they can harm Wisconsin producers by raising prices on raw materials or components that they import, such as steel or aluminum, the report added. Additionally, Trump’s tariffs have prompted retaliation that makes U.S. exports more expensive — at the risk of prompting foreign companies to drop Wisconsin suppliers.  

Wisconsin’s top exports are particularly vulnerable to retaliatory tariffs: industrial and electrical machinery, accounting for $10.9 billion or nearly 40% of state exports in 2024, according to the Wisconsin Policy Forum.

A New York Times analysis shows that Wisconsin workers may be among those hit hardest by retaliatory tariffs because affected industries support so many jobs in the state. 

“Economists don’t agree on anything except for tariffs. You put a hundred economists in the room, and you ask them are tariffs a good policy —  and 99 of them are going to tell you, no,” Deller said. “This is bad policy. At least the way that Trump is doing it. Everybody loses.”

DataWatch: Record spending. Record turnout. We crunched some numbers from the Supreme Court contest

The April 1 Wisconsin Supreme Court election was the most expensive U.S. court race in history, drawing more than $100 million in campaign spending

That eye-popping figure has drawn plenty of headlines — as did the millions spent by billionaire Elon Musk to support Republican-backed Waukesha County Judge Brad Schimel, who lost handily to Dane County Judge Susan Crawford, backed by Democrats.

But the race also set another record in Wisconsin for a spring election not featuring a presidential primary contest: in voter turnout. 

More than 2.3 million people cast ballots in the election, according to Associated Press tracking. That amounts to nearly 51% of the voting age population, shattering the previous record for such elections of 39% in 2023.

The high turnout is part of a trend in Wisconsin politics since President Donald Trump’s first election in 2016, Marquette University’s John Johnson wrote in an analysis last week.

“Wisconsin’s electorate is just plain extremely engaged,” he wrote. “Scour American history and you’ll struggle to find an example of (a) state as hyper-engaged with, and narrowly divided by, electoral politics as Wisconsin in the present moment.” 

Last week’s election offered good news for Democrats, aside from the top-line figures in Crawford’s 55%-45% win. (The Supreme Court is officially nonpartisan, but Democrats backed Crawford, while Republicans backed Schimel.) 

When comparing the high-turnout 2024 presidential election to the latest Supreme Court race, voting shifted toward the Democratic-backed candidate in all 72 counties.

The biggest difference in the latest election, according to Johnson: “A majority of the million voters who stayed home are probably Republicans, or at least Trump supporters.” 

More broadly, it’s clear that the high stakes of the Supreme Court race drove most to cast ballots in an election that also included an officially nonpartisan contest for state superintendent of public instruction and a successful ballot measure to enshrine voter ID requirements in the Wisconsin Constitution. 

Nearly 200,000 people who cast ballots did not choose a superintendent candidate. Democratic-backed incumbent Jill Underly prevailed over Republican-backed Brittany Kinser by a 53%-47% margin — closer than the Supreme Court race. 

Additionally, about 76,000 voters did not weigh in on the voter ID amendment.
