CDC recommends additional COVID-19 vaccine shot for immunocompromised individuals

On Friday, August 13, 2021, the Centers for Disease Control & Prevention (CDC) announced new recommendations that people who are moderately or severely immunocompromised receive an additional dose (“third shot”) of the mRNA COVID-19 vaccines they received.

This is what you should know about an additional shot for immunocompromised people:

  • People who are moderately to severely immunocompromised need a third shot because they are especially vulnerable to COVID-19 due to being more at risk of serious and prolonged illness.
  • People with moderately to severely compromised immune systems may not build the same level of immunity from just two doses of Pfizer and Moderna vaccines compared to people who are not immunocompromised.
  • This third dose is not the same as a booster dose given to people when their immune response to a primary vaccine series is likely to have waned over time.
  • People who are immunocompromised, or who are not sure if they are, should contact their healthcare provider to determine whether and when to receive a third dose.
