Vaccination against influenza is recommended every year, for anyone wanting to lower their chance of catching influenza.

How does

FLUCELVAX® QUAD vaccine works by helping your body to protect itself against infection by the types of influenza viruses that are in the vaccine. The vaccine stimulates the body to make substances called antibodies.

Antibodies fight the influenza virus.

If you have been vaccinated, when you come into contact with the influenza viruses in the vaccine, your body is usually able quickly to destroy the virus, which may prevent you from getting influenza.

As with all vaccines, 100% protection cannot be guaranteed.

Influenza is caused by infection with specific influenza viruses. New types of influenza viruses can appear each year. FLUCELVAX® QUAD vaccine contains fragments of four different types of influenza virus. Each year the World Health Organization decides which four types of viruses are most suitable to include in the vaccine.

You cannot catch influenza from the vaccine, as the virus in the vaccine has been killed and split into small non-infectious particles.
