The Centers for Disease Control and Prevention (CDC) recently updated its guidance to shorten the COVID-19 booster shot waiting time for moderately or severely immunocompromised patients receiving either the Pfizer-BioNTech or Moderna mRNA vaccines.
The CDC now says Pfizer-BioNTech vaccine recipients 12 and older and Moderna vaccine recipients 18 and older can get a booster shot three months after completing the two-dose COVID-19 vaccine series and receiving the third dose (additional primary dose), down from the previously recommended five-month intervals.
Moderate to severely immunocompromised individuals 18 and older who received a single dose of the Johnson & Johnson (J&J) vaccine should receive an additional dose of a Pfizer-BioNTech or Moderna vaccine 28 days after the J&J vaccine. A booster shot of either of the Pfizer-BioNTech or Moderna vaccine is recommended two months after the second shot. That time frame has not changed.
