Who should not get FluMist?
You should not get FluMist if you: are allergic to eggs, gentamicin, gelatin, or arginine; have ever had a life-threatening reaction to influenza vaccinations; or are 2 through 17 years old and take aspirin or medicines containing aspirin. Children under 2 years of age should not get FluMist because there is a chance they may wheeze (difficulty with breathing) after getting FluMist.
