The Centers for Disease Control and Prevention (CDC) has clarified the COVID-19 vaccination schedule for people who are moderately to severely immunocompromised to better protect them from the potential severe consequences of COVID-19. These changes are designed to eliminate confusion about vaccine recommendations and to help ensure they have optimal protection against SARS-CoV-2, the virus that causes COVID-19.

CDC guidance for COVID-19 vaccination includes the following for people who are moderately or severely immunocompromised:

  • An update that people who have completed a primary series of an mRNA vaccine (Pfizer-BioNTech or Moderna) are recommended to receive an mRNA booster dose 3 months (instead of 5 months) after the last primary dose.
  • An update that people who have received a single Johnson & Johnson’s Janssen COVID-19 vaccine should receive one additional dose of an mRNA COVID-19 vaccine and one booster dose (preferably mRNA) for a total of 3 vaccine doses.
  • A clarification of a current recommendation to confirm that those who have completed their primary series of 3 mRNA doses should receive an mRNA vaccine booster dose—to make a total of 4 doses.
  • People who previously received passive COVID-19 antibody products (monoclonal antibodies) do not need to wait for any period prior to COVID-19 vaccination.

People who are moderately or severely immunocompromised have lower vaccine effectiveness, and their vaccine protection wanes over time. They may not develop protective immunity after a primary series, even when the recommended 3-dose mRNA vaccine primary series is used. People who are moderately or severely immunocompromised can receive all doses anywhere vaccines are offered, and proof is not needed.
