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.

Facts About the Seasonal Flu

The flu is a contagious respiratory illness caused by the influenza virus. Symptoms can vary from mild to severe illness, and can at times even include death.

Since 2010, the CDC estimates between:

  • 140,000 and 710,000 flu related hospitalizations; 
  • 12,000 and 56,000 flu related deaths.

Some people, such as older people, young children, and people with certain health conditions, are at increased risk for serious flu complications.

The single best way to reduce your chance of suffering from the flu is to get a flu vaccination each year.

  • 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.

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.

All persons aged 6 months and older are recommended for annual vaccination, with rare exception.

Vaccination to prevent influenza is particularly important for people who are at high risk for serious complications from influenza. See People at High Risk of Developing Flu–Related Complications for a full list of age and health factors that confer increased risk.

  • If you have an allergy to eggs or any of the ingredients in the vaccine. Talk to your doctor about your allergy.
  • If you ever had Guillain-Barré Syndrome (a severe paralyzing illness, also called GBS). Some people with a history of GBS should not get this vaccine. Talk to your doctor about your GBS history.

Yes, each year's flu shot is formulated differently. Therefore, each year's vaccine will protect you from slightly different circulating flu viruses. It is important to get your flu shot every year. Last year's flu shot will not provide you with sufficient immunity this year.
