Different Types of Flu Vaccines
Note: “Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices — United States, 2019–20 Influenza Season” has been published. CDC recommends annual influenza vaccination for everyone 6 months and older with any licensed, influenza vaccine that is appropriate for the recipient’s age and health status, (IIV, RIV4, or LAIV4) with no preference expressed for any one vaccine over another. Content on this website is being updated to reflect this most recent guidance. More information about the upcoming 2019-2020 flu season is available.
Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are in the vaccine. The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season. Below are links to more information about the different type of flu vaccines available.
The flu shot is a vaccine given with a needle, usually in the arm.
The quadrivalent flu vaccine is designed to protect against four different flu viruses.
The high dose vaccine contains 4 times the amount of antigen as a regular flu shot and is licensed specifically for people 65 years and older.
Cell-based vaccines are grown in cultured cells of mammalian origin instead of in hens' eggs.
The intradermal flu vaccine is a shot that is injected into the skin instead of the muscle.
Live Attenuated Influenza Vaccine [LAIV] is given as a nasal spray.
Flu vaccination via jet injector is approved for use in people 18 through 64 years of age.
Adjuvanted flu vaccine is made with an additive that creates a stronger immune response and is licensed specifically for people 65 years and older.
Recombinant flu vaccines are produced using a method that does not require an egg-grown vaccine virus.
