Mechanism of action
This inactivated influenza vaccine contains antigens from four influenza virus strains (two A subtypes and two B lineages) that trigger both humoral and cellular immune responses. Upon vaccination, the body produces strain-specific antibodies and memory B cells that recognize and neutralize circulating influenza viruses, reducing infection risk and severity.
Approved indications
