The Wisconsin Department of Health Services (DHS) has released its annual vaccination rates among children, adolescents, and adults for 2025. The data show Wisconsin’s childhood vaccination rates continued to decrease last year. While nearly 7 of every 10 children (66.9%) had the recommended vaccinations at age 24 months, nearly 3 of every 10 did not. This is a decline of almost 2% from 2024.
“In public health, we use data like this as an alert system. Today that alert system is sending a clear signal that the health and well-being of Wisconsin kids and communities is at risk,” said Paula Tran, state health officer and Division of Public Health administrator. “Vaccination rates aren’t just numbers on a chart, they represent real people—children, families, and neighbors. Even small declines in vaccination rates increase the risk of preventable diseases spreading and outbreaks occurring.”
