Mechanism of action

The vaccine contains inactivated (killed) hepatitis A virus antigen that triggers both humoral and cellular immune responses. This leads to the production of protective antibodies (anti-HAV IgG) and memory B cells, conferring long-term immunity against hepatitis A infection. The 720 junior formulation contains a lower antigen dose (360 ELISA units per 0.5 mL dose) designed for pediatric use.
