What is influenza?

  • Influenza, or the flu, is a contagious respiratory virus that can cause mild to severe disease. It can sometimes lead to death.

  • Common symptoms are fever, cough, shaking chills, body aches, and extreme weakness.

Why should someone get the flu vaccine?

  • Vaccination is the best way to protect yourself and those around you.

  • Getting the flu vaccine reduces the chance that you will be seriously ill if you do get sick with the flu.

  • The flu vaccine will not make you sick with the flu.

  • People with chronic health conditions, older adults, young children, and pregnant women are at higher risk of developing serious flu-related complications.

Who SHOULD get the flu vaccine?

  • Everyone 6 months and older should get the flu vaccine every year, with rare exceptions.

  • Children 6 months through 8 years of age may need 2 doses during a single flu season.

Who should NOT get the flu vaccine?

  • Children younger than 6 months of age.

  • People with severe, life-threatening allergies to the flu vaccine or any ingredient in the vaccine.

Who should talk with their healthcare provider before getting the flu vaccine?

  • If you have an allergy to eggs or any of the ingredients in the vaccine. See Special Considerations Regarding Egg Allergy for more information about egg allergies and flu vaccine.

  • If you ever had Guillain-Barré Syndrome (a severe paralyzing illness, also called GBS).

  • If you are not feeling well, talk to your doctor about your symptoms.
