Vaxigrip is a vaccine used to prevent influenza, commonly known as the flu. It helps protect against infection by the influenza virus, which can cause symptoms such as fever, cough, sore throat, body aches, and fatigue. Vaxigrip works by stimulating the body’s immune system to produce antibodies against the influenza virus strains included in the vaccine. It is typically administered annually, as the flu virus strains can change from year to year, and the vaccine formulation is updated accordingly. Vaxigrip is recommended for individuals aged 6 months and older, especially those at higher risk of complications from influenza, such as older adults, young children, pregnant women, and individuals with certain medical conditions. It is usually administered as an injection into the muscle, commonly in the upper arm.
