Hepatitis Vaccination Guidelines for Travelers

Introduction to Hepatitis Vaccination

The Centers for Disease Control and Prevention (CDC) recommends that previously vaccinated adults in their late 30s and early 40s traveling to high-risk areas do not need booster doses for either hepatitis A or hepatitis B before travel 1, 2

Hepatitis A vaccination provides long-lasting, likely lifelong immunity after completing the 2-dose series, and the CDC's Advisory Committee on Immunization Practices (ACIP) does not recommend booster doses for immunocompetent adults who have completed the primary vaccination series 1, 2
For travelers aged 12 months to 40 years who are healthy and previously unvaccinated, only one dose is recommended before travel, with no requirement for immune globulin 1, 2, 3

Hepatitis B vaccination provides long-term protection in immunocompetent adults, and routine booster doses are not recommended, with the CDC stating that persons who have completed a HepB vaccination series at any point or who have a history of HBV infection should not receive additional HepB vaccination 4
After completing the primary series, >90% of healthy adults aged <40 years develop protective antibody levels that persist for decades 5
The only exceptions requiring booster consideration are special populations, including hemodialysis patients, healthcare providers with ongoing exposure risk, and certain immunocompromised individuals 5

If vaccination records are unavailable or uncertain, serologic testing for anti-HAV IgG and anti-HBs can confirm immunity, and lack of documentation should not delay travel—revaccination of previously immune individuals is safe and causes no harm 4
For travelers over age 40 who were never vaccinated, the CDC recommends one dose of hepatitis A vaccine before travel, with optional immune globulin based on provider risk assessment 1, 2, 3
