What you need to know
- CDC recommends that people with moderately to severely compromised immune systems receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of Pfizer-BioNTech COVID-19 vaccine or Moderna COVID-19 vaccine.
- People with moderately to severely compromised immune systems are especially vulnerable to COVID-19, and may not build the same level of immunity to 2-dose vaccine series compared to people who are not immunocompromised.
- This additional dose is intended to improve immunocompromised people’s response to their initial vaccine series.
- No testing or doctor’s note is needed to determine eligibility. Self-attestation is all that is necessary.
- Although CDC does not recommend additional doses or booster shots for any other population at this time, HHS has announced a plan to begin offering COVID-19 vaccine booster shots this fall.
- DHEC sent a letter to vaccine providers to ready them for this federal recommendation.
- A booster dose is not recommended for everyone at this time is because FDA and CDC are examining the data to determine the optimal timing of a booster. If you get a booster too soon after your second shot you may not get the best immune response.
Who Needs an Additional COVID-19 Vaccine?
Currently, CDC is recommending that moderately to severely immunocompromised people receive an additional dose. 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 high-dose corticosteroids or other drugs that may suppress your immune response
- People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them.
