Biovac A Vaccine is a preventive injection that offers protection against Hepatitis A, a contagious liver infection caused by the hepatitis A virus (HAV). This disease spreads through the ingestion of contaminated food or water, particularly in areas with poor sanitation. Biovac A is an inactivated (killed) viral vaccine, designed to train the immune system to fight the virus without causing the disease itself. The vaccine is administered intramuscularly, usually in the upper arm (deltoid muscle), and typically requires only one dose for adequate long-term protection. The vaccine is safe, effective, and plays a crucial role in controlling hepatitis A outbreaks and preventing severe liver complications.

How Biovac A works
Biovac A contains a weakened strain of the hepatitis A virus. After injection, the immune system recognizes the virus as foreign. It begins to produce specific antibodies that fight against hepatitis A. These antibodies remain in the body and offer protection in the future. If the person is exposed to the real virus later, the body responds quickly. The immune system destroys the virus before it causes illness. This trained response prevents infection and liver complications. The vaccine works best when given before any exposure to the virus. A single dose is enough to build strong immunity in most people.
