CDC Advises Moderately or Severely Immunocompromised Teens, Adults to Get Fourth COVID-19 Shot
The Centers for Disease Control and Prevention (CDC) advised that moderately or severely immunocompromised teens and adults receive a total of four doses of COVID-19 vaccine. The four doses are made up of a primary series of three doses of an mRNA COVID-19 vaccine, plus one booster of an mRNA COVID-19 vaccine (fourth dose).
|Primary Series COVID-19 Vaccine||Age Group||No. of Doses to Complete Primary Series and Timing||Booster and Timing|
|Pfizer-BioNTech||12+ years||3 doses: 2nd dose given 3 weeks (21 days) after 1st dose||1 booster given ≥3 months after 3rd dose|
|Moderna||18+ years||3 doses: 2nd dose given 4 weeks (28 days) after 1st dose; 3rd dose given ≥4 weeks (28 days) after 2nd dose||1 booster given ≥3 months after 3rd dose|
If the individual teen or adult with a moderately or severely immunocompromised status has received the one-dose J&J/Janssen vaccine, the CDC advises they get a second dose of either Pfizer-BioNTech or Moderna COVID-19 vaccine (mRNA vaccines) and also receive a booster, for a total of three doses.
