COVID-19 vaccine third doses

People who are moderately to severely immunocompromised are especially vulnerable to COVID-19 because they are more at risk of serious, prolonged illness. The FDA has authorized a third dose of COVID-19 vaccine for certain immunocompromised individuals.

Who is eligible to receive an additional dose?

The CDC recommends that people whose immune systems are compromised moderately to severely receive an additional dose of mRNA (Pfizer-BioNTech or Moderna) COVID-19 vaccine after the initial two doses. Tidelands Health only administers the Pfizer-BioNtech vaccine.

How do I know if I need an additional dose?

Click here to review the CDC guidance. An additional 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?

Per CDC guidance, the additional dose of mRNA vaccine should be administered at least four weeks after the second dose of Pfizer or Moderna vaccine.

Can I mix and match COVID-19 vaccines when I receive my 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.

I received the Johnson & Johnson/Janssen vaccine. Should I receive another dose?

At this time, the FDA authorization only applies to mRNA (Pfizer and Moderna) vaccines.

Where can I receive an additional dose at Tidelands Health?

Tidelands Health offers the COVID-19 vaccine on a walk-in basis at three regional vaccination sites. For locations, hours and more, please click here.

    Patients may also receive the COVID-19 vaccine at Tidelands Health Family Medicine locations with a regularly scheduled appointment.

    How much does an additional dose cost?

    There is no cost to you to receive the COVID-19 vaccine.

    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 (Pfizer or Moderna) and the date of your second dose. A doctor’s note or prescription for a third dose is not required. Self-attestation is all that is necessary to verify eligibility.

    What are the age criteria to receive an additional dose?

    The age criteria remain the same as for the initial series. You must be at least 12 years old to receive the Pfizer vaccine.

    Which COVID-19 vaccine is Tidelands Health offering?

    At this time, we are administering the Pfizer-BioNTech vaccine (Comirnaty) at our regional vaccination sites, physician offices and mobile clinics.
