Influenza (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 used to make vaccine. The seasonal flu vaccine protects against the influenza viruses that research suggests may be most common during the upcoming season. Below are links to more information about the different type of flu vaccines available.
Flu shots are vaccines given with a needle, usually in the arm.
Quadrivalent flu vaccines protect against four different flu viruses.
The high dose vaccine contains 4 times the amount of antigen (the part of the vaccine that helps your body build up protection against flu viruses) 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.
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 old.
Adjuvanted flu vaccine is made with an ingredient added to a vaccine that helps create 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.
