Get Vaccinated

	Flu vaccination can be received as soon as the vaccine is available, usually by October.

Protection from flu vaccination sets in after 2 weeks.

Who should get vaccinated this season?

Everyone 6 months of age and older should get a flu vaccine every season. Vaccination to prevent influenza is particularly important for people who are at high risk of 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.

Flu vaccination has important benefits. It can reduce flu illnesses, doctors' visits, and missed work and school due to flu, as well as prevent flu-related hospitalizations.

Different flu vaccines are approved for use in different groups of people. Factors that can determine a person's suitability for vaccination, or vaccination with a particular vaccine, include a person's age, health (current and past) and any relevant allergies.

Flu shots are approved for use in pregnant women and people with chronic health conditions.  There are flu shots that also are approved for use in people as young as 6 months of age and up.

The nasal spray vaccine is approved for use in people 2 years through 49 years of age.

More information is available at Who Should Get Vaccinated Against Influenza.

    • Children age 2-17 receiving aspirin therapy
    • Pregnant women

When should I get vaccinated?

CDC recommends that people get vaccinated against flu soon after vaccine becomes available, if possible by October. It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu.

People who have ever had a severe allergic reaction to eggs can get recombinant flu vaccine if they are 18 years and older or they should get the regular flu shot (IIV) given by a medical doctor with experience in management of severe allergic conditions. People who have had a mild reaction to egg—that is, one which only involved hives—may get a flu shot with additional safety measures. Recombinant flu vaccines also are an option for people if they are 18 years and older and they do not have any contraindications to that vaccine. Make sure your doctor or health care professional knows about any allergic reactions. Most, but not all, types of flu vaccine contain a small amount of egg.
