Vaccination rates for influenza and COVID-19 are low in Wisconsin, and on Thursday, the Wisconsin Department of Health Services announced that two children have died within the last month: one from the flu in northeast Wisconsin and one from COVID-19 in the western part of the state.

Citing concerns for family privacy, DHS is not releasing the ages of the children. At a media briefing, Tom Haupt, the DHS respiratory epidemiologist, said they were the first deaths of people under 18 from those illnesses since the start of the flu season Oct. 1.

Although year-to-year comparisons in mid-season are difficult, “we are definitely seeing an increase in influenza and COVID-19 at this particular point,” Haupt said.

Haupt said DHS has not yet verified whether either of the two children were vaccinated. Both had “some underlying conditions that would increase their risk” for more serious illness, he said.

Five people under 18 died from flu in January and early February 2025, Haupt said. DHS monitors certain illnesses, including flu and COVID-19, through data from hospital emergency rooms, lab tests and studying municipal wastewater for evidence of the viruses responsible.

Vaccination is the best tool for preventing serious illness from both flu and COVID-19, Haupt said.

“Our vaccination status for children for both COVID-19 and influenza are very low,” he said. “We want them to be increased significantly.”

Across all ages, about 28% of Wisconsinites have been vaccinated against the flu and 10.6% against COVID-19. “These numbers are lower than what we’ve seen over the past few years and that’s very unfortunate,” Haupt said.

DHS recommends both vaccines for everyone 6 months or older. The COVID-19 and the flu shots can both be given at the same time.

Flu can have outcomes much worse than its usual symptoms.

“Influenza could lead to cardiac problems for both children and adults. It can lead to encephalitis,” Haupt said. “So, it’s not only the acute acute part of influenza, it’s what can happen later on.” With vaccination people are “protecting yourself and protecting those people who are around you.

For a third serious respiratory illness, respiratory syncytial virus, or RSV, DHS recommends the maternal RSV vaccine for expectant mothers who are 32 to 36 weeks pregnant, to protect their infants after they’re born.

DHS recommends the RSV vaccine for infants younger than 8 months if they were born to mothers who did not get the vaccine during pregnancy. DHS also recommends the vaccine for children 8 to 19 months old with a higher risk of RSV, as well as for adults 75 and older and for adults 50 to 74 years old who have an increased risk for the virus.

Haupt said doctors have told DHS that they’re encountering more vaccine hesitancy in the general public than in the past. One cause appears to be confusion about shifting recommendations from the federal Centers for Disease Control and Prevention and the CDC advisory council that makes recommendations on vaccines, he said.

Haupt said that for people hesitating about getting vaccines for themselves or their children, the “most accurate sources” for information are the state health department, local public health departments, community clinics, pharmacies and primary care doctors.
