The best way to prevent the flu is by getting vaccinated each year.

CDC recommends that everyone 6 months of age and older get their yearly flu vaccine now. Flu vaccine is especially important for infants, young children, pregnant women, adults over 50, and for those with chronic conditions.

Flu virus is mainly spread through droplets from coughs and sneezes. Remember these important everyday steps to help stop the spread of germs:

  • cover your cough with a sleeve or tissue
  • wash your hands often
  • stay home if you are sick

CDC recommends everyone 6 months of age and older get their yearly flu vaccine now. While everyone should get a flu vaccine each flu season, it's especially important certain people get vaccinated either because they are at high risk of having serious flu-related complications or because they live with or care for people at high risk for developing flu-related complications. These groups include:

  1. Pregnant women
  2. Children younger than 5 years—especially children younger than 2 years old
  3. People 65 years of age and older
  4. People of any age with certain chronic medical conditions (more information here)

  7. Health care workers
  8. Household contacts of persons at high risk for complications from the flu
  9. Household contacts and out of home caregivers of children less than 6 months of age (these children are too young to be vaccinated)

There are two types of flu vaccine:

Tell your doctor if you have any severe (life-threatening) allergies, including a severe allergy to eggs. More information on the influenza vaccine.
