COVID-19 Vaccine Third Doses
As our region’s leader in COVID-19 vaccination and response, Tidelands Health is offering a third dose of the COVID-19 vaccine in alignment with CDC guidelines.
A third dose is administered to people who are moderately to severely immunocompromised who did not build enough protection when they first received the vaccine. A third dose should be administered at least four weeks after the second dose.

Who is eligible to receive a third dose?
Emerging data have demonstrated that immunocompromised people who have low or no protection following two doses of mRNA COVID-19 vaccines may have an improved response after an additional dose of the same vaccine.
- Pfizer vaccine: The CDC recommends that people ages 5 and older whose immune systems are compromised moderately to severely receive an additional dose of mRNA Pfizer COVID-19 vaccine at least 28 days after completing the initial two doses.
- Moderna vaccine: The CDC recommends that people 12 and older whose immune systems are compromised moderately to severely receive an additional dose of mRNA Moderna COVID-19 vaccine at least 28 days after completing the initial two doses.
The FDA’s emergency use authorization for a third dose only applies to mRNA COVID-19 vaccines, as does CDC’s recommendation. There is not enough data at this time to determine whether immunocompromised people who received the Johnson & Johnson vaccine also have an improved antibody response following an additional dose of the same vaccine.
However, the CDC does recommend all individuals 18 and older who received the Johnson & Johnson vaccine receive a booster dose at least two months after the initial dose.
How do I know if I need a third dose?
Per the CDC, a third dose is recommended for moderately to severely immunocompromised people. 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 two 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 high-dose corticosteroids or other drugs that may suppress your immune response
How long should I wait after my first and second doses to receive a third dose?
For immunocompromised individuals seeking a third dose, CDC guidance states that the additional dose of mRNA vaccine should be administered at least four weeks after the second dose of Pfizer or Moderna vaccine.
Where can I receive a third dose at Tidelands Health?
Tidelands Health offers the Pfizer vaccine on a walk-in basis at three regional vaccination sites. For locations, hours and more, please click here.
Patients may also receive the vaccine at Tidelands Health Family Medicine and Tidelands Health Pediatrics locations with a regularly scheduled appointment.
How much does a third dose cost?
There is no cost to you to receive the COVID-19 vaccine.
Can I mix and match COVID-19 vaccines when I receive my third dose?
For immunocompromised individuals seeking a third dose, the CDC recommends people receive a third dose of the same mRNA (Pfizer or Moderna) vaccine originally received. If the vaccine product you received for the first two doses is not available, you may receive the other mRNA vaccine. At this time, the FDA authorization for third dose vaccine for immunocompromised individuals only applies to mRNA (Pfizer and Moderna) vaccines.
Do I need to bring anything with me to receive a third dose?
Please bring your COVID-19 vaccination record. Or, if your card is not available, please let our registration staff know at check-in the brand of vaccine you initially received and the date of your second dose. A doctor’s note or prescription for a booster dose or third dose is not required. Self-attestation is all that is necessary to verify eligibility.
Which COVID-19 vaccine is Tidelands Health offering?
Tidelands Health is offering the Pfizer-BioNTech vaccine for the third dose. Individuals seeking a third dose of the Moderna vaccine can find a provider via the South Carolina DHEC website by clicking here.
Am I eligible to receive a booster dose?
People who are immunocompromised are especially vulnerable to COVID-19, which is why the CDC has authorized a third dose of the COVID-19 vaccine as part of the primary series of vaccinations for some people with moderately to severely compromised immune systems.
In addition, the CDC encourages some individuals with moderately to severely compromised immune systems to receive a booster dose of the COVID-19 vaccine after completing their primary, three-dose series of vaccinations. At Tidelands Health, we are administering this fourth dose to eligible individuals at our vaccination locations listed here.
