Doses taken at least 2 weeks before travel is protective in nearly 95% of people.

If you have less than 2 weeks before travel:
  1. If you are less than 40 years of age and healthy, 1 dose of Hepatitis A vaccine (Havrix or Vaqta) any time prior to departure gives some protection. Finish the series upon return for lifelong protection.
  2. If you are greater than 40 years of age,are immunocompromised or have chronic liver disease we recommend1 dose ofHepatitis A vaccine (Havrix or Vaqta) + Immune globulin 0.02 ml/kg intramuscular injection (at a separate injection site) for protection, any time prior to travel. Finish the series upon return for lifelong protection.
  3. If you are allergic to the vaccine or its components (egg), Immune globulin 0.06 ml/kg intramuscular injection any time before trip likely provides protection for 3 months.

Always:

Follow safe water and food recommendations.

Hepatitis A Vaccine can be taken with other vaccines, antibiotics or immune globulin products.
