Vaccines and Booster Doses for Moderately or Severely Immunocompromised People
It is especially important for you to stay up to date with your vaccinations and boosters if you have a weakened immune system. You may find that your response to the vaccine is not as strong as that of people who are not immunocompromised.
There are specific vaccination recommendations for children ages 5-11 and for pre-teens, teens, and adults who are moderately or severely immunocompromised.
Booster doses are recommended for anyone over age 12 after completing their primary vaccine series, even if they were younger than 12 at that time.
