There have been many questions about the need for a vaccine booster or additional doses to increase COVID immunity following initial vaccination. See below to learn more about the difference between booster shots, a third dose, and the eligibility for each.

Covid-19 vaccine boosters

For immunocompromised patients:

A third dose of the vaccine has been approved for use in people who are moderately to severely immunocompromised.You can find more information on who is eligible to receive a third dose on the CDC website.

Third doses can be administered as early as 28 days after a second dose, and are reserved only for those with a weakened immune system who may not have mounted a full response to the initial two shots of the vaccine. If you're unsure about whether a third dose of the vaccine is appropriate for you, talk to your primary care provider.

For patients who are not immunocompromised:

The White House and Centers for Disease Control and Prevention (CDC) recently announced that booster shots will be available in September for individuals who have been fully vaccinated against COVID-19.Booster shots are meant to be a supplemental boost to your immune system's initial response to the vaccine. Anyone who received their vaccine more than eight months ago should be eligible to receive a booster shot.

Main Line Health will be offering—but not mandating—booster shots to our staff beginning in September. After an initial rollout to our staff, we will also make booster shot appointments available to our community or you can obtain a booster at your local pharmacy.
