The Centers for Disease Control and Prevention (CDC) recently recommended that certain high-risk groups get boosters of the Pfizer-BioNTech vaccine against COVID-19.

The advice came after U.S. health officials and advisers analyzed the results of research that suggests immunity declines over time for people who have the original two doses of the vaccine.

The CDC previously had recommended a third dose for people with weakened immune systems who had received the Pfizer or Moderna vaccines because the vaccines did not work as well in these groups. The new advice applies to a much larger portion of the U.S. population.

Eric Sachinwalla, MD, Medical Director of Infection Prevention and Control for Einstein Medical Center Philadelphia, offers the following advice for people who may be eligible to receive boosters.
