2 or 3 shot series: Hepatitis a vaccines come in 2-shot and 3-shot series. Sometimes, hepa and hepb vaccines are combined in the same shot.

Like most others...: The hepa vaccine is administered via the intramuscular route. It is one of the recommended vaccinations for children since 2006 and confers long term immunity to the virus. There is extensive information about HAV and immunization against it available on the cdc website. (www.Cdc.Org). Hope this is helpful.

The HepA schedule.: Calls for two doses of vaccine separated i. Time. Immunity begins to develop 2-4 weeks after immunization. Therefore vaccination should be given at least this far in advance to confer protection. Once established, immunity is estimated to last 15-25 years.
