Fluad Tetra is used to prevent influenza in people aged 50 years and older.

The vaccine is directed against four strains of the influenza virus, following the recommendations of the World Health Organization for the 2024/2025 season.

------------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

Medical treatment and adequate supervision should always be readily available in case of an anaphylactic episode, which can rarely occur after vaccine administration.

Shake gently before use. After shaking, the normal appearance of the vaccine is a white, cloudy suspension.

The vaccine should be inspected visually for particulate matter and/or changes in physical appearance before administration. If particulate matter and/or changes in physical appearance are observed, do not administer the vaccine.

If a prefilled syringe is supplied without a needle, remove the protective cap from the tip of the syringe and attach a suitable needle for administration. For LuerLock syringes, remove the protective cap from the tip of the syringe by unscrewing it in an anticlockwise direction. Once the protective cap is removed, attach a needle to the syringe by screwing it in a clockwise direction until it is secure. When the needle is securely attached, remove the needle protector and administer the vaccine.
