Vaccines and Preventable Diseases:
Seasonal Influenza (Flu) Vaccination
Pronounced (in-floo-EN-za)
The single best way to protect against the flu is to get vaccinated each year. There are two types of vaccines:
1. The "flu shot"— an inactivated vaccine (containing killed virus) that is given with a needle, usually in the arm. The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions. More...
2. The nasal-spray flu vaccine — a vaccine made with live, weakened flu viruses that do not cause the flu (sometimes called LAIV for “live attenuated influenza vaccine” or FluMist®). LAIV (FluMist®) is approved for use in healthy* people 2-49 years of age† who are not pregnant. More...
The viruses in the vaccine change each year based on international surveillance and scientists' estimations about which types and strains of viruses will circulate in a given year.
