Mechanism of action

The vaccine contains inactivated (killed) influenza virus particles or viral components that trigger both humoral (antibody) and cell-mediated immune responses. Upon vaccination, B cells produce neutralizing antibodies against viral surface antigens (hemagglutinin and neuraminidase), while T cells develop memory to recognize infected cells. This pre-existing immunity reduces infection risk and severity if exposure to circulating influenza strains occurs.
