What is it and how is it used?

Fluenz is a vaccine to prevent influenza (flu). It is used in children and adolescents 24 months to less than 18 years of age. When a person is given the vaccine, the immune system (the body?s natural defence system) will produce its own protection against the influenza virus. None of the ingredients in the vaccine can cause the flu.

Fluenz vaccine viruses are grown in chicken eggs. The vaccine targets three strains of influenza virus each year, following the annual recommendations by the World Health Organisation.


What do you have to consider before using it?

You will not be given Fluenz

  • if you are allergic to eggs, egg proteins, gentamicin, or gelatin or any of the other ingredients of Fluenz (theseare listed in section 6 ?Further Information?). For signs of allergic reactions, see section 4 ?Possible side effects?.
  • if you havea blood disorder or a cancer that affects the immune system.
  • if you have been told by your doctor that you have a weakened immune system as a result of a disease, medicine, or other treatment.
  • if you are under 18 years of age and already taking acetylsalicylic acid(a substance present in many medicines used to relieve pain and lower fever). This is because of the risk of a very rare but serious disease (Reye?s syndrome).

If any of these apply, tell your doctor, nurse or pharmacist.

Take special care with Fluenz
