Vaccination exemption rates for US kindergartners hit record high
Key Points:
- The CDC reported a decline in vaccination rates among kindergartners during the 2025-2026 school year, with the MMR vaccine rate dropping to 92.4%.
- Nonmedical exemptions for vaccines reached a record 4% nationwide, contributing to an overall increase in exemptions for at least one vaccine.
- Among 46 states with sufficient data, 42 experienced a rise in nonmedical exemption rates, with 23 states reporting rates of 5% or higher.
- The data covers vaccination rates for MMR, DTaP, polio, and chickenpox vaccines and was released shortly after President Donald Trump signed an executive order aimed at spacing out child vaccinations.
