FDA approves FluMist for self- or caregiver-administration, the first influenza vaccine not needing a health care provider. FluMist, for individuals 2-49, prevents flu caused by virus subtypes A and B. It was initially approved in 2003 for ages 5-49 and expanded in 2007 to include 2-5-year-olds. The vaccine, sprayed into the nose, offers convenience and accessibility. Side effects include fever, runny nose, nasal congestion, and sore throat. FluMist will be available via third-party online pharmacies, with a caregiver administering it to those aged 2-17.
