Denver, CO, August 18, 2026 —
Kindergarten vaccination rates across the United States have seen a consistent decline over the past four years, coinciding with a record high in vaccine exemptions, primarily for nonmedical reasons. According to recent data, these exemptions have now reached 4.2% nationwide.
Experts attribute this downward trend in vaccination coverage to confusion surrounding current vaccination recommendations. This confusion appears to be impacting immunization rates for several key diseases. Notably, measles vaccination rates have fallen, contributing to an increase in measles outbreaks. The past year has been identified as the worst year for measles outbreaks since 1991.
While the rate of medical exemptions for vaccinations has remained stable, nonmedical exemptions have seen a significant increase in many states. The prevalence of these nonmedical exemptions varies widely across the country. Idaho reports the highest rate of nonmedical exemptions, standing at 17.5%, while Connecticut has one of the lowest, with rates below 0.5%.
The rise in nonmedical exemptions and the concurrent decline in vaccination rates raise public health concerns, particularly regarding the potential resurgence of preventable diseases. Health officials continue to monitor these trends and emphasize the importance of vaccination for maintaining community immunity.
