Mechanism of action

This vaccine contains inactivated (killed) influenza virus particles or antigens from three circulating influenza strains (typically two A strains and one B strain). When administered, it triggers both humoral and cellular immune responses, leading to the production of strain-specific antibodies and memory B cells. Upon exposure to wild-type influenza virus, these pre-existing antibodies neutralize the virus and prevent or reduce the severity of infection.
