About the Seasonal Flu Shot

The seasonal flu vaccine protects against three influenza viruses that research indicates will be most common during the upcoming season. 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. About 2 weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body.

Yearly flu vaccination should begin in September, or as soon as vaccine is available, and continue throughout the flu season which can last as late as May. This is because the timing and duration of flu seasons vary. While flu season can begin as early as October, most of the time seasonal flu activity peaks in January, February or later.
