High Risk Groups

Everyone 6 months of age and older should receive the influenza vaccine. But the CDC says that some groups run a higher risk for severe complications of the flu, including people who:

  • Are 6 months to 5 years of age
  • Are 50 years or older
  • Have chronic medical conditions
  • Are immunosuppressed
  • Are or will be pregnant during flu season (See our page, “Flu During Pregnancy”)
  • Are 6 months to 18 years of age and receiving long-term aspirin therapy
  • Are residents of nursing homes or chronic care facilities
  • Are American Indians/Alaskan Natives
  • Are morbidly obese (with a Body Mass Index of 40 or higher)
  • Work in health care
  • Are household contacts and caregivers of children 5 years of age or under, adults 50 years of age and older, and people with medical conditions that put them at higher risk for severe complications of flu.

If you or a loved one is in a high risk group for complications of flu, make sure to get your yearly flu shot as early as possible each flu season.

Learn more about flu vaccine safety and find a flu vaccine clinic in your local area.
