Flu vaccine

Types of Flu vaccine

There are two types of flu vaccines:

  • "Flu shots"—inactivated vaccines (containing killed virus) that are given with a needle. There are three flu shots being produced for the United States market now.
  • The nasal-spray flu vaccine—a vaccine made with live, weakened flu viruses that is given as a nasal spray (sometimes called LAIV for "Live Attenuated Influenza Vaccine"). The viruses in the nasal spray vaccine do not cause the flu. LAIV is approved for use in healthy people 2 to 49 years of age who are not pregnant.
