A 3rd dose of an mRNA vaccine (either Pfizer or Moderna) for immunocompromised people was recently approved by the FDA. If you are taking a medication that suppresses your immune system, please contact your CCAO provider to discuss whether you are a candidate for a 3rd shot. At this time, J&J has submitted their data to the FDA, but there are no recommendations for getting a 2nd J&J shot if that was the initial vaccine.
