Covid-19 3rd Dose Versus Booster

Learn more about the COVID-19 Vaccine recommendations 3rd Dose versus Booster.

 

Booster

A COVID booster shot is an additional dose of a vaccine given after the protection provided by the original shot(s) has begun to decrease over time. Typically, you would get a booster after the immunity from the initial dose(s) naturally starts to wane. The booster is designed to help people maintain their level of immunity for longer.

 

3rd dose

A third dose of the mRNA COVID-19 vaccines (Pfizer or Moderna) is identical to the first two doses. It can help protect people with weakened immune systems who did not have a strong enough response to the first two doses of one of the mRNA vaccines. Such people can get a third dose as soon as 28 days after a second dose. The FDA has authorized, and the CDC recommends, that those with certain medical conditions that suppress the immune system get a third dose of the same brand of COVID-19 vaccine that they initially received.
