Vaccine exemptions for religious or personal beliefs are rising among U.S. kindergarteners

A JAMA study using data compiled by NBC News and Stanford found median nonmedical exemption rates for kindergartners rose from 0.6% in 2010–11 to 3.1% in 2023–24, and more than half of counties reported post‑pandemic increases.

Researchers report an increase in kindergarten vaccine exemptions claimed for religious or personal beliefs across much of the United States. The finding is published in JAMA and is based on a data investigation by NBC News with Stanford University. The analysis covered 3,053 counties and jurisdictions across 45 states and the District of Columbia from 2010 through 2024. Study authors noted the increase accelerated after the COVID‑19 pandemic and a co‑author described the trend as concerning. Key findings: - The study analyzed exemption data from 3,053 counties and jurisdictions in 45 states plus the District of Columbia for 2010–2024. - Median nonmedical exemption rates rose from 0.6% in 2010–2011 to 3.1% in 2023–2024. - More than 53% of counties reported an increase of more than 1% in nonmedical exemptions after the pandemic. - Medical exemption rates remained stable, and the report did not state any scheduled legal or procedural actions. Summary: Authors reported a measurable increase in nonmedical vaccine exemptions among kindergarten entrants, with higher concentrations in certain states and localities. Undetermined at this time.
