Joshua Kline, MD, chief medical officer, PPG – Family Medicine, explains how a third dose or booster shot can help protect the population against COVID-19.

An additional or third dose is particularly beneficial for those who have a compromised immune system. The booster can offer an additional layer of protection for those who are fully vaccinated, as protection from the initial vaccines can wane over time.  

Experts recommend a booster six months after the initial Pfizer or Moderna vaccine series, or two months after the Johnson & Johnson vaccine. According to the Centers for Disease Control and Prevention (CDC), you do not need to get the same kind of vaccine for your booster as you did for your initial vaccine series.
