This vaccine works by safely stimulating the body's natural defenses. Vaxigrip Tetra causes your body to produce its own protection (antibodies) specifically targeted against four different types of circulating influenza virus (two influenza A strains and two influenza B strains) anticipated for the current flu season. This preparation ensures you are protected if you encounter the actual virus.
