Moderately or severely immunocompromised people age 5 or older who received an initial mRNA COVID-19 vaccine primary series should receive an additional primary dose of the same mRNA COVID-19 vaccine at least 28 days after the second dose. Get more information from the Centers for Disease Control and Prevention. Please talk to your doctor if you have questions.
Booster shots are recommended for those who are:
- 12 and older and completed their primary vaccination series of Pfizer at least 5 months ago
- 18 and older and completed their primary vaccination series of Moderna at least 5 months ago or completed their primary vaccination of Johnson & Johnson at least 2 months ago
If you are age 12-17, you must receive the Pfizer booster as it is the only vaccine approved for this age group. If you are 18 or older, you may choose to receive the Johnson & Johnson (Janssen), Moderna or Pfizer booster.
Moderately and severely immunocompromised people 12 or older who completed an mRNA COVID-19 vaccine primary series and received an additional mRNA vaccine dose should receive a single COVID-19 booster dose (Pfizer-BioNTech, Moderna or Janssen) at least 5 months after completing their third mRNA vaccine dose. In such situations, people who are moderately and severely immunocompromised may receive a total of four COVID-19 vaccine doses. A person who received one primary dose of Johnson & Johnson (Janssen) COVID-19 vaccine should not receive more than two COVID-19 vaccine doses. A patient’s clinical team is best positioned to determine the appropriate timing of vaccination.
