1. Contents of the pack and further information

1. What is Fluarix Tetra and what is it used for

Fluarix Tetra is a vaccine that helps protect you against influenza, particularly in people with a high risk of complications. The use of Fluarix Tetra should be based on official recommendations.

When Fluarix Tetra is administered to a person, their immune system (the body's natural defense system) will produce its own protection (antibodies) against the disease. None of the vaccine components can cause influenza.

Influenza is a disease that spreads quickly and is caused by different strains that can change each year. This is why you may need to be vaccinated every year. The period with the highest risk of contracting influenza is during the cold months, between October and March. If you were not vaccinated in the autumn, it is recommended that you do so before spring, as you are at risk of infection until then. Your doctor will recommend the best time to be vaccinated.

Fluarix Tetra will protect you against the four virus strains from approximately 2 to 3 weeks after injection.

The incubation period of influenza is a few days, so if you are exposed to influenza immediately before or after vaccination, you can still develop the disease.

The vaccine will not protect you against the common cold, even though some of the symptoms are similar to those of influenza.

2. What you need to know before you receive Fluarix Tetra

To ensure that Fluarix Tetra is suitable for you, it is important that you inform your doctor or pharmacist if any of the following points apply to you. If there is anything you do not understand, ask your doctor or pharmacist to explain.

Do not use Fluarix Tetra

• If you are allergic to the active substances or to any of the other components of this medicine (listed in section 6) or to any component that may be present in very small amounts such as eggs (ovoalbumin or chicken proteins), formaldehyde, gentamicin sulfate, or sodium desoxycholate.
• If you have any disease accompanied by high fever or acute infection, vaccination should be delayed until you have recovered.

Warnings and precautions

Consult your doctor or pharmacist before receiving Fluarix Tetra:

Your doctor will decide if you should receive the vaccine.

Before or after any injection, fainting (especially in adolescents) may occur, so you should inform your doctor or nurse if you have fainted after receiving an injection in the past.
