In 2006 Hepatitis A vaccination was incorporated into the routine childhood vaccination schedule. Therefore many adults did not receive the Hepatitis A vaccine as a child. There are specific groups that should be vaccinated as adults so be familiar with the list below. Keep in mind that post-exposure prophylaxis for HAV is available. Unvaccinated individuals who are exposed to HAV should receive a single-antigen HAV vaccine or immune globulin within two weeks of the exposure.

Administer missing doses to complete a 2 dose series (0, 6 months)
If the immunization schedule is interrupted the 2nd dose can be given without restarting the series.
