US Kindergarten Vaccination Rates Decline, Exemptions Reach Record High

Data released by the Centers for Disease Control and Prevention (CDC) indicates a downward trend in routine childhood vaccination rates among children entering kindergarten for the 2025-2026 school year. Concurrently, the number of vaccination exemptions filed by parents has reached an unprecedented peak.

The CDC’s findings, which track vaccination status for students entering kindergarten, reveal a decline in the coverage of several key immunizations typically required for school entry. While specific percentages for the current school year were not detailed in the summary, the overall trend points to lower vaccination rates compared to previous years.

In parallel with the decrease in vaccinations, the rate of non-medical exemptions for childhood immunizations has climbed to a new record high. These exemptions, which can include philosophical or religious reasons depending on state laws, allow children to enroll in school without meeting all vaccination requirements.

The report does not specify the exact vaccination rates or the precise number of exemptions. It also does not provide a breakdown of exemption types or reasons. Further details regarding the specific vaccines affected and the geographic distribution of these trends were not immediately available.

Public health officials often cite high vaccination rates as crucial for maintaining herd immunity, which helps protect entire communities, especially those who cannot be vaccinated due to age or medical conditions. Declining vaccination rates and rising exemptions are frequently linked to an increased risk of vaccine-preventable disease outbreaks in school settings.

The CDC periodically releases data on childhood immunization coverage and exemption rates. These reports are critical for monitoring public health trends and informing vaccination policies and public health initiatives aimed at ensuring high immunization coverage across the United States.
