SPECIAL BULLETIN COVID-19 #195: Booster Dose of Pfizer, Moderna and Janssen Vaccines
Update on booster shot doses, codes and payment

Update on COVID-19 booster shot recommendations for Pfizer, Moderna and Janssen

On Oct 20, 2021, the Federal Drug Administration (FDA) recommended for individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at six months or more after their initial series:

For those who got the Janssen (Johnson & Johnson) COVID-19 vaccine, booster shots are also recommended for those who are 18 and older and who were vaccinated two or more months ago.

More information on the FDA’s authorization is available for the Moderna vaccine and the Janssen vaccine.

Eligible individuals may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type that they originally received and others may prefer to get a different booster. The Centers for Disease Control’s (CDC’s) recommendations now allow for this type of mix and match dosing for booster shots. NC Medicaid beneficiaries should talk to their health care provider about whether getting a COVID-19 booster shot is appropriate for them.

Beginning Oct 20, 2021, NC Medicaid vaccine providers may begin administering the booster dose of COVID-19 vaccine to those beneficiaries who qualify and by self-attestation. Payment amount will be equivalent to other doses of the COVID-19 vaccine at $40 each.
