Mechanism of action
FluQuadri contains inactivated (killed) virus particles or viral antigens from four influenza strains (two A strains and two B strains). When administered, it triggers the adaptive immune response, leading to production of neutralizing antibodies and cellular immunity against these circulating influenza variants. This provides protection against infection by matching the vaccine composition to predicted seasonal flu strains.
