According to data from the Centers for Disease Control and Prevention, 4.2% of kindergartners in the US, approximately 155,000 children, had at least one vaccine exemption during the 2025-26 school year, up from 3.6% the previous year. The majority of these exemptions were labeled as "non-medical", meaning parents opted out for personal or religious reasons rather than health concerns. This marks a trend that began during the COVID pandemic, with 41 states and Washington D.C. reporting increases in exemptions. Measles cases reached a 35-year high in 2026, with over 2,500 reported cases nationwide.

Story summary
In the 2025-26 school year, about 155,000 kindergartners in the US had at least one vaccine exemption, a record high according to data from the Centers for Disease Control and Prevention (CDC). This represents 4.2% of all kindergartners, up from 3.6% the previous school year. The majority of these exemptions were labeled as "non-medical," meaning parents or caregivers opted out of vaccines for personal or religious reasons, rather than health reasons. This trend is particularly concerning because it reflects a rise in families resisting school vaccine requirements that began during the height of the Covid pandemic. 41 states and Washington D.C. reported increases in exemptions. The CDC data comes just after President Donald Trump signed an executive order to reduce the number of recommended childhood vaccinations, which has been widely criticized by pediatricians and public health advocates.
