Association Between State Hepatitis A Vaccination Requirements and Hepatitis A Vaccination Rates

Using National Immunization Survey Child and Teen (2008-2017), we associated state vaccination requirements with hepatitis A (Hep A) vaccination rates in children and adolescents. States with school entry or both childcare and school entry requirements were associated with 35%-40% higher Hep A vaccination rates, compared with states without such requirements. Children and adolescents residing in states with school entry or both childcare and school entry requirements had 35%-40% higher hepatitis A vaccination coverage rates, compared with those residing in states without such requirements.
