What is Fluarix Tetra?

Fluarix Tetra is a vaccine which is designed to protect against flu viruses. It has been specially treated so that it will not cause disease but will encourage the immune system (the body’s natural defence system) of the person vaccinated to fight the influenza virus if they become infected.

How does it work?

Fluarix Tetra is a vaccine which helps protect you or your child against influenza (flu). It is useful in subjects who, because of their age, pregnancy or some other condition, may be at special risk of illness if they are infected by the flu virus.

When a person is given a vaccine, the immune system will produce its own protection (antibodies) against the disease. None of the ingredients in the vaccine can cause the disease.

The flu vaccine cannot protect patients against the common cold even though some of the symptoms are similar to flu.

How is it given?

Fluarix Tetra is given as a one 0.5ml dose by injection into the muscle, usually in the upper arm.

Fluarix Tetra is suitable for use in adults and children from three years of age.

For children under nine years, who have not been previously vaccinated against flu, a second dose should be given after an interval of at least four weeks.

Flu is a disease that can spread rapidly and is caused by different types of strains that can change every year. Due to this, the specific strains which go into the production of the vaccine change annually, and this is why you or your child will need to be vaccinated every year to continue to be protected from flu.

For further information on this influenza vaccine please see the Fluarix Tetra Patient Information Leaflet (PIL).
