Fluarix Tetra is a vaccine that protects you from the flu and is especially helpful for those at high risk of severe complications from the flu.
Adults and children from 6 months of age receive one 0.5 ml dose. Children under 9 years old who have not been vaccinated against the flu before need a second dose at least 4 weeks after the first.
The doctor will give the vaccine as an injection into a muscle, usually in your arm.
One dose at a time as prescribed by your doctor.
