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.
