Inactivated Hepatitis A vaccine is used to protect adults and children from 12 months of age against infection caused by the Hepatitis A virus, by building the body's own immunity (active immunization).
Pharmacology
The hepatitis A virus belongs to the picornavirus family. It is one of several hepatitis viruses that cause disease throughout the body, with the damage showing up in the liver. The incubation period for hepatitis A averages 28 days (range: 15 to 50 days). The course of the infection varies a great deal, from no symptoms at all to icteric hepatitis and death. Antibodies to HAV protect against hepatitis A infection, but the lowest titer needed for protection has not been determined.
