Fluarix is an immunization against influenza (“the flu”) virus types A and B. It is made by GlaxoSmithKline and approved for people over 3 years old. There are two types of Fluarix:
- Fluarix Trivalent: Protects against 3 types of influenza viruses (two type A strains and one type B strain) and it was approved in 2005.
- Fluarix Quadrivalent: Protects against 4 types of influenza viruses (two type A strains and two type B strains) and it was approved in 2012.
For children between 3 years and 8 years old, Fluarix is given in one 0.5-mL dose. Children who have never received a flu shot should get two doses of the 0.5-mL Fluarix vaccine given at least 4 weeks apart.
Children over 9 years old and adults should get one 0.5mL dose of Fluarix. The preferred injection site is the upper arm (deltoid muscle).
No. Fluarix has inactivated (dead) influenza viruses that can’t cause infection with the flu. Some people do develop mild flu-like symptoms as their body develops immunity, but it is not the flu.
Fluarix is contraindicated in anyone with a history of severe allergic reaction (e.g., anaphylaxis) to egg protein, any previous flu shot, or any other ingredient in Fluarix (see below for a complete list).
Carefully consider the risks and benefits of Fluarix in anyone who developed Guillain-Barré Syndrome within 6 weeks of a flu shot.
