The steady erosion of childhood vaccination rates isn’t simply a statistical trend; it’s a harbinger of preventable disease outbreaks and a reflection of a growing disconnect between public health recommendations and parental choices. New data from the Wisconsin Department of Health Services, released March 9, reveals a concerning continuation of this decline: approximately 67% of Wisconsin children received the recommended series of seven vaccines by their 24-month checkup in 2025, down from 69% in 2024 and a peak of nearly 73% in 2017. While a 2-percentage point drop might appear modest, Stephanie Schauer, the state’s immunization program manager, clarified that this translates to roughly 1,200 fewer children protected against potentially life-threatening illnesses. This isn’t an isolated Wisconsin problem, but the state’s data provides a starkly localized illustration of a national vulnerability.
The vaccines in question cover a broad spectrum of diseases – diphtheria, tetanus, pertussis, polio, measles, mumps, rubella, Haemophilus influenzae type b, hepatitis B, chickenpox, pneumonia, and meningitis – and are tracked through the Wisconsin Immunization Registry. The decline isn’t limited to the overall series completion rate; individual vaccine coverage is also slipping. Notably, measles, mumps, and rubella (MMR) vaccination rates among Wisconsin 2-year-olds fell below 80% in 2025 for the first time in over a decade, dropping from over 88% in 2013. This is particularly alarming given the current national measles outbreak, with over 1,200 cases reported in 2026, overwhelmingly affecting unvaccinated individuals. The resurgence of measles, a disease once considered largely eradicated in the U.S., underscores the direct consequences of declining immunization rates. Paula Tran, Wisconsin state health officer, rightly characterizes the data as signaling a risk to the health and well-being of both children and their communities.

However, framing this solely as a matter of individual choice overlooks the complex forces at play. Declining rates predate 2025, escalating during the COVID-19 pandemic as routine healthcare visits were disrupted. But the trend has persisted, fueled by the spread of misinformation, financial barriers to healthcare access, and, increasingly, political rhetoric. The appointment of Robert F. Kennedy Jr. as U.S. Health and Human Services Secretary in 2025 represents a significant shift in federal policy. Kennedy Jr. has a long history of questioning vaccine safety and efficacy, and his leadership has already resulted in the CDC reducing the number of recommended vaccines for children – a decision Wisconsin health officials actively disagree with, continuing to align with the recommendations of the American Academy of Pediatrics. This divergence between federal and state guidance creates confusion and potentially undermines public trust in established scientific consensus.
It’s crucial to understand what the study actually found versus what headlines might suggest. The data doesn’t establish a causal link between Kennedy Jr.’s appointment and the drop in Wisconsin’s vaccination rates – correlation does not equal causation. However, the timing is undeniably concerning, and his vocal skepticism likely contributes to an environment where vaccine hesitancy can flourish. Furthermore, the data reveals significant regional disparities within Wisconsin. Brown County boasts a relatively high coverage rate of 77.5%, while Vernon and Clark counties lag far behind at 35.2% and 32.5% respectively. This suggests that localized factors, such as access to healthcare and community attitudes, play a critical role in vaccination uptake. Milwaukee County falls in the middle, with 65.2% coverage.
Limitations to consider include the reliance on the Wisconsin Immunization Registry, which, while comprehensive, may not capture all vaccinations administered outside of traditional healthcare settings. Additionally, the data only reflects vaccination rates up to age 2; long-term trends require monitoring vaccination status throughout childhood and adolescence. The state is actively working to address barriers to vaccination through programs like Vaccines for Children, offering free or low-cost vaccines through over 700 providers, and by funding community-based initiatives that meet parents where they are. Expanding pharmacy participation in the Vaccines for Children program is another key strategy.
Looking ahead, the critical question isn’t simply whether vaccination rates will recover, but how public health officials can rebuild trust and address the underlying factors driving hesitancy. Will targeted interventions in counties with low coverage, like Vernon and Clark, prove effective? And, perhaps more importantly, will the ongoing measles outbreak – and the real-world consequences experienced by affected families – serve as a powerful counter-narrative to misinformation, or will it further entrench existing beliefs? The next year will be pivotal in determining whether Wisconsin, and the nation, can reverse this dangerous trend and protect its youngest citizens from preventable diseases.
