HEPATITIS A VACCINES

HEPATITIS A VACCINES

As countries prosper, anti-HAV seroprevalance decreases; that is why infection is more commonly encountered in advanced age cases in developed countries. The presence of the risk of developing fulminant hepatitis and the increase in touristic travels to endemic areas, emphasizes the importance of active immunization. Studies for preparing a vaccine started in the late 70's and the first vaccine was introduced in 1992.
