6.Contents of the package and additional information

Fluenz is a vaccine to prevent the flu. It is used in children and adolescents over24months andless than18years. Fluenz will help protect you from the virus strains contained in the vaccine and other closely related strains.

How Fluenz works

When the vaccine is administered to a person, the immune system (the body's natural defense system) produces its own protection against the flu virus. None of the vaccine components can cause the flu.

The Fluenz virus strains are grown in chicken eggs. Each year, the vaccine acts against three flu strains, following the annual recommendations of the World Health Organization.

You will not be given Fluenz:

• if you are allergicto gentamicin, gelatin orany of the other components of this vaccine (these are listed in the section6“Contents of the package and additional information”).
• if you have ever had asevere allergic reactionto eggs or egg proteins. To know the signs of allergic reactions, see the section4“Possible side effects”.
• if you have ablood disorderor acancerthataffects the immune system.
• ifyour doctor has toldyou that you havea weakened immune systemas a result ofan illness, medication or other treatment.
• if you are already takingaspirin(a substance present in many medications used to relieve pain and reduce fever).This is due to the risk of a rare but seriousReye's syndrome.

If any of these conditions apply to you,inform your doctor, nurse or pharmacist.
