Mechanism of action

The quadrivalent inactivated influenza vaccine contains antigens from four influenza virus strains (two A subtypes and two B lineages) that trigger both humoral and cell-mediated immune responses. Upon vaccination, the immune system recognizes these viral antigens and generates protective antibodies and memory T cells that provide immunity against infection by these circulating influenza strains.
