Major Changes To Childhood Vaccine Schedule Announced By CDC: What To Know In WI

MADISON, WI — The Centers for Disease Control and Prevention took the unprecedented step Monday of dropping the number of vaccines it recommends for every child, adopting a policy that gives Wisconsin parents choice but very little guidance.

Officials said the overhaul to the federal vaccine schedule won't result in any families losing access or insurance coverage for vaccines, but medical experts slammed the move, saying it could lead to reduced uptake of important vaccinations and increase disease.

Wisconsin requires students enrolled in K–12 schools to be up to date on vaccines, including polio, hepatitis B, DTaP/Tdap, MMR, and varicella, with meningococcal (MenACWY) vaccination required at seventh grade and a booster by 12th grade.

State law allows exemptions for medical, religious, or personal conviction reasons, though documentation rules apply, including stricter verification for prior chickenpox infections

The new vaccine schedule is similar to Denmark’s and recommends children get vaccines for 11 diseases, compared with the 18 the CDC previously recommended. The changes are effective immediately.

The change, which officials acknowledged was made without input from an advisory committee that typically consults on the vaccine schedule, came after President Donald Trump in December asked the U.S. Department of Health and Human Services to review how peer nations approach vaccine recommendations and consider revising its guidance to align with theirs.

HHS said its comparison to 20 peer nations found that the U.S. was an "outlier" in both the number of vaccinations and the number of doses it recommended to all children. Officials with the agency framed the change as a way to increase public trust by recommending only the most important vaccinations for children to receive.

“This decision protects children, respects families, and rebuilds trust in public health,” Health Secretary Robert F. Kennedy Jr. said in a statement Monday.

Medical experts disagreed, saying the change without public discussion or a transparent review of the data would put children at risk.

“Abandoning recommendations for vaccines that prevent influenza, hepatitis and rotavirus, and changing the recommendation for HPV without a public process to weigh the risks and benefits, will lead to more hospitalizations and preventable deaths among American children,” said Michael Osterholm of the Vaccine Integrity Project, based at the University of Minnesota.
