Mechanism of action

The vaccine contains inactivated (killed) influenza virus particles representing four circulating influenza strains (two A subtypes and two B lineages). Upon intramuscular injection, these antigens trigger both humoral and cellular immune responses, leading to the production of strain-specific antibodies and T-cell immunity that protect against infection with matching influenza viruses.
