FluMist® is a vaccine approved for the prevention of certain types of influenza disease in children, adolescents, and adults 2-49 years of age. FluMist may not protect everyone who gets it. FluMist is for intranasal administration only.

FluMist is not right for everyone. FluMist must not be given to: people with history of hypersensitivity to eggs, egg proteins, gentamicin, gelatin, or arginine; people with life-threatening reactions to previous influenza vaccinations; and children and adolescents receiving aspirin or aspirin-containing therapy.

Children less than 24 months of age are not eligible for FluMist.
