Fluarix Tetra FAQs

How often do I need to have a flu vaccine?

Flu is a disease that is caused by different types of strains that can change every year. Therefore, this is why you or your child might need to be vaccinated every year.

When should I get vaccinated?

The greatest risk of catching flu is during the cold months between October and March. Make an appointment at your surgery or pharmacy as soon as their flu clinics begin, this will usually be around September. If you or your child were not vaccinated in the autumn, it might still be appropriate to be vaccinated up until the spring since the flu virus may still be around and able to infect you.

Can Fluarix Tetra give me the flu?

Fluarix Tetra has been specially treated so that it will not cause disease but will encourage the body’s natural defence system (immune system) to fight influenza if you become infected. None of the ingredients in the vaccine can cause the disease.

Will I have any reactions?
