Indications for a Booster Dose Following mRNA COVID-19 Primary Series

The Advisory Committee on Immunization Practices (ACIP) voted October 21, 2021 to recommend a booster dose following mRNA (Moderna and Pfizer) COVID-19 primary series. Individuals may self-report that they are eligible and receive a booster shot wherever vaccines are offered. If a Moderna vaccine booster is administered, the booster dose volume will be a half dose. Studies have shown that amount will give us a great immune response without the intense symptoms that some people had for a day or so after their previous vaccination.

DA’s Authorization of Heterologous (Mix-and-Match) Booster Dose FDA amended the EUAs for COVID-19 vaccines to allow for the use of each of the available COVID-19 vaccines as a heterologous (or “mix and match”) booster dose in eligible individuals following completion of primary vaccination with a different available COVID-19 vaccine. CDC’s recommendations now allow for this type of mix and match dosing for booster shots. Heterologous dosing may be considered for the booster dose only.
