1. What is Flucelvax and what is it used for

Flucelvax is an influenza vaccine. Flucelvax is prepared in cell cultures and therefore does not contain egg.

When a person receives the vaccine, the immune system (the body's natural defense system) will produce its own protection against the influenza virus. None of the vaccine components can cause influenza.

Flucelvax is used to prevent influenza in adults and children from 6 months of age.

The vaccine is directed against three strains of the influenza virus, following the recommendations of the World Health Organization for the 2025/2026 Campaign.
