Kindergarten vaccination and exemption rates by state
Vaccination coverage among kindergartners in the 2024–25 school year for MMR (measles, mumps, rubella; 2 doses), DTaP (diphtheria, tetanus, pertussis), polio, hepatitis B and varicella (up to date with the doses the state requires, or a history of the disease), and the shares of kindergartners with any exemption and a non-medical exemption from one or more required vaccines, as reported by state immunization programs to CDC (SchoolVaxView). Blank where a vaccine is not required for school entry in the state, or (for non-medical exemptions) where the state does not allow them. States differ in their survey methods (census or sample), school types covered and documentation rules, so CDC cautions against close comparisons; the national figures are CDC's aggregate.
