Kindergarten Vaccination Status in California After Changes to Medical Exemption Policy
This study in California analyzed vaccination data after the implementation of Senate Bills 276 and 714 (SB276) in 2019, which tightened oversight of medical exemptions for school-entry vaccinations. While medical exemptions decreased significantly, the overall percentage of kindergarteners not up to date on vaccinations increased. The rise was attributed to disruptions during the COVID-19 pandemic and parents opting for non-vaccination modalities like homeschooling. Despite reduced medical exemptions, the increase in non-vaccinated children indicated a replacement effect. Enhanced monitoring is recommended to ensure timely vaccinations for children affected by pandemic disruptions.
