FluMist is the brand name of an influenza virus vaccine that is administered as a nasal spray. It contains live, attenuated (changed to not cause infection) influenza viruses, and is used to prevent infection by the influenza virus. FluMist works by exposing a person to a small dose of the virus so that the immune system develops antibodies against the disease. However, a CDC panel concluded in 2016 that the vaccine has not been effective in recent year, and did not recommend its use for the 2016-2017 flu season.
