About Hepatitis B Vaccine.

Hepatitis B vaccines constitute an established pharmacologic class of active immunizing agents designed to prevent infection caused by the hepatitis B virus (HBV).

These biological products primarily utilize recombinant hepatitis B surface antigen (HBsAg) to stimulate an active immune response, inducing the production of specific neutralizing anti-HBs antibodies and conferring long-term protection against the virus.

The class is indicated for pre-exposure immunization in infants, children, adolescents, and adults, as well as for post-exposure prophylaxis following occupational, perinatal, or mucosal exposures.

By preventing acute HBV infection, these vaccines effectively avert the progression to chronic hepatitis B, cirrhosis, and hepatocellular carcinoma.
