Third Dose for Immunocompromised Individuals

Content

On Aug. 13, 2021, the CDC published recommendations that people who are moderately to severely immunocompromised should receive an additional third dose of mRNA COVID-19 vaccine 28 days after receiving the primary two dose series.

  • A third dose of the Pfizer vaccine is authorized for people 12 years and older who are moderately to severely immunocompromised
  • A third dose of the Moderna vaccine is authorized for people 18 years and older who are moderately to severely immunocompromised.

About 2.7 percent of Americans have a condition or receive treatment that meets this definition. More details can be found here: COVID-19 Vaccines for Immunocompromised People.

Please note the third dose is different than the booster dose.
