Vaccine Types

Moderna and Pfizer Booster: The Centers for Disease Control (CDC) has authorized boosters of the Pfizer and Moderna Covid-19 vaccines for all adults age 18 and over at least six months after completing the primary mRNA 


Johnson & Johnson (Janssen) Booster: Anyone aged ≥18 years who received a single dose Johnson & Johnson primary series (1 dose) can receive a COVID-19 booster dose at least 2 months after completing the primary series. J&J vaccine does not have eligibility criteria for the booster dose.

Mix and Match Use:The Food and Drug Administration (FDA) amended the Emergency Use Authorizations 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. Mix and match dosing may be considered for the booster dose only.

Third dose: The CDC recommends moderately to severely immunocompromised people receive an additional dose of COVID-19 vaccine. Please review the guidance for who may recieve a third dose here. The third dose should be the same product as the initial 2-dose mRNA COVID-19 primary vaccine series. The third dose recommendation only applies to mRNA COVID-19 vaccines (Moderna and Pfizer), and does not include Johnson & Johnson’s Janssen COVID-19 vaccine.
