The CDC said in updated guidelines Tuesday that some immunocompromised people who have received either the Pfizer or Moderna vaccine will be able to get a fourth shot.

“Moderately and severely immunocompromised people aged ?18 years who completed an mRNA COVID-19 vaccine primary series and received an additional mRNA vaccine dose may receive a single COVID-19 booster dose (Pfizer-BioNTech, Moderna or Janssen) at least 6 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 is moderately or severely immunocompromised and has received two doses of an mRNA vaccine and ?28 days has elapsed since the second dose, should receive an additional mRNA dose immediately (if Moderna COVID-19 vaccine is used, administer 100µg in 0.5ml), followed ?6 months later by a single COVID-19 vaccine booster dose (if Moderna vaccine booster is used, administer 50µg in 0.25ml).”
