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.
Based on the CDC’s most recent recommendations, people who are immunocompromised who have received a bivalent COVID-19 vaccine may receive a single additional dose of a bivalent COVID-19 vaccine at least 2 months following the previous dose. Additional doses may be administered at the discretion of their healthcare provider.
Immunocompromised children 6 months through 4 years of age may also be eligible for additional doses of the updated bivalent booster, depending on vaccine history.
