About The Study: This study identified an increase in nonmedical exemptions to childhood vaccination requirements from 2010 to 2024, with wide variation among counties and states and an increase following the COVID-19 pandemic, which may contribute to resurgence of vaccine-preventable diseases. This county-level analysis reveals geographically focused areas of high vaccine exemptions that are less evident at the state level.
