Fluad Tetra


influenza vaccine (surface antigen, inactivated, adjuvanted)

This medicine is authorised for use in the European Union.


Fluad Tetra is a vaccine used to protect people aged from 65 years against influenza (flu).

Flu is caused mainly by two types of influenza virus, known as influenza A and B. Each of these circulate as different strains, which change over time.

Fluad Tetra will contain proteins from four different inactivated influenza A and B virus strains (two strains of type A influenza virus of the subtypes H1N1 and H3N2 and two type B strains). They are chosen according to the official recommendation for the annual flu season.

The vaccine also contains an adjuvant, which helps to improve the vaccine's effectiveness. The viruses used for producing Fluad Tetra are grown in fertilized hens’ eggs.
