Early this year, we launched our first-ever Long COVID Clinic to provide comprehensive care to individuals who have been affected by the long-term effects of COVID-19.
The COVID Clinic is led by Dr. Sarah Ali, Director of Infectious Diseases, with additional support from other departments.
Depending on the initial assessment and specific needs, the care team might also coordinate access to additional specialties.

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 them maintain their immunity and protect against getting sick, just like 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., a third dose of Pfizer or Moderna) should also receive a booster when they are eligible.
Does my booster need to be the same vaccine I had originally?
The FDA has determined that receiving a booster or additional dose that is a different brand than the initial vaccine is safe. 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). Children and teens ages 5+ 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 5-11 years old, you can get a booster at least five months after your second shot.
If you originally got the 3 doses of the Pfizer vaccine and you are 5-11 years old and immunocompromised, you can get a booster at least three months after your second shot.
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, immunocompromised, and 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:
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.
FDA has authorized updated boosters (Bivalent) for those 6mths- 4years.
FDA has authorized updated boosters (Bivalent) for those 6mths- 4years.
Children within this age group who completed their 3-dose primary series with the monovalent Pfizer vaccine more than two months ago are now eligible to receive Pfizer Bivalent as a single booster. This authorization is specific to the subset of individuals who completed their series before the last Pfizer 6mth-4year update, which authorized Bivalent as a 3rd dose in the primary series.
*Children who have completed the updated primary series with Bivalent as a 3rd dose, are not eligible for a booster as they are expected to have the protection from the most serious COVID-19 outcomes. This group is currently up to date.
ELIGIBILITY:
*Those 6 months -4 yrs. who have completed their primary series with Moderna are ONLY eligible for a Booster dose w/ a Moderna vaccine. No mixed matching for this age group. This a reminder that Mary’s Center carries Pfizer COVID-19 products only.
The Pfizer vaccine is approved for children ages 5-11, and the CDC is now also recommending booster shots for children ages 5-11 at least five months after their second dose, or three months after the second dose for immunocompromised children.
What’s the process to get children vaccinated?
Established Mary’s Center participants ages 5-11 who are already coming into our clinics for other appointments will be offered the vaccine.
We are also offering walk-in vaccines and vaccine appointments for children ages 5-11. See schedules above.
How can parents make an appointment for their children’s vaccine?
Parents can call our 24-hour appointment line at 844-796-2797.
Is there a cost for the vaccine for children?
No, the vaccine is free. If patients have insurance, we ask for their insurance cards.
