Booster Shots and Additional Doses

What is the difference between a booster shot and an additional dose?

Over time, immunity from your initial dose(s) of the COVID-19 vaccine naturally starts to wane. Booster shots are recommended for certain vaccinated people to help you maintain your immunity to protect against getting sick, just like getting tetanus boosters.

For people with compromised immune systems, they may need an additional dose of the vaccine to build up the same level of immunity as people who are not immunocompromised. Those who receive an additional dose (e.g., third dose of Pfizer or Moderna) should also receive a booster when they are eligible.

Does my booster or third dose need to be the same vaccine I had originally?

The FDA has determined that it is safe to receive a booster or additional dose that is a different brand than the initial vaccine. That means you can mix and match, getting whichever vaccine is available for your booster or third dose.

For second booster shots, the CDC recommends getting one of the mRNA vaccines (Pfizer or Moderna). Teens ages 12+ are only eligible for the Pfizer booster. Mary’s Center is currently offering Pfizer at all sites unless otherwise noted. See more details above.

Who needs a first booster shot of the COVID-19 vaccine?

If you originally got the 2-dose Pfizer vaccine and you are 16 or older, you can get a booster at least six months after your second shot. If you are 12-15 years old, you can get a booster five months after your second shot.

If you originally got the 2-dose Moderna vaccine and you are 18 or older, you can get a booster at least six months after your second shot.

If you originally got the 1-dose Johnson & Johnson vaccine and you are 18 or older, you can get a booster at least two months after your shot.

The CDC especially recommends the booster for people over 50 and those living in long-term care settings.

See the information above to make an appointment or walk in to receive your booster.

Who needs a second booster shot of the COVID-19 vaccine?

If you are 50 or older and you received your first booster shot at least four months ago, you are eligible for a second booster shot.

If you are 12 or older and immunocompromised, and you received your first booster shot at least four months ago, you are eligible for a second booster shot.

If you originally got both a Johnson & Johnson vaccine and booster, and you are 18 or older, you are eligible for a second booster at least four months after your first booster.

See the information above to make an appointment or walk in to receive your booster.

Who needs a third dose of the COVID-19 vaccine?

Currently, CDC is recommending that moderately to severely immunocompromised people who received Pfizer or Moderna for their initial vaccine receive an additional dose (of Moderna or Pfizer only). This includes people who have:

  • Been receiving active cancer treatment for tumors or cancers of the blood
  • Received an organ transplant and are taking medicine to suppress the immune system
  • Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection
  • Active treatment with oral high-dose corticosteroids or other drugs that may suppress your immune response

If you fall into one of these categories, see the information above to make an appointment or walk in to receive your third dose. If you’re not sure if you qualify, please ask your oncologist, rheumatologist, or primary care clinician.
