Booster Doses Authorized for Moderna and Johnson & Johnson Vaccine Recipients

Wednesday, October 27, 2021
Following FDA approval, recommendations from the CDC’s Advisory Committee on Immunization Practices (ACIP) and the endorsement of the CDC director, the Michigan Department of Health and Human Services (MDHHS) is urging certain Michiganders to get a booster vaccine if they received the Moderna or Johnson & Johnson (J&J) primary COVID-19 vaccines. This includes people ages 65 and older; individuals 18 through 64 years of age at high risk of severe COVID-19 due to underlying health conditions; and those at high risk of COVID-19 due to occupational or institutional exposure.

There are now booster recommendations for all three available COVID-19 vaccines in the United States. Eligible individuals may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type they originally received and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.

For individuals who received an mRNA (Pfizer-BioNTech or Moderna) COVID-19 primary vaccine, the following groups are eligible for a booster shot at six months or more after their initial series:

People over age 18 who received a single dose of the J&J (Janssen) vaccine should receive a single J&J COVID-19 booster dose at least two months after completing their primary series.

  • The use of a single booster dose of the J&J COVID-19 vaccine may be administered at least two months after completion of the single-dose primary regimen to individuals 18 years of age and older.

Per CDC, occupations at increased risk for COVID-19 exposure and transmission include frontline essential workers and health care workers including:

  • First responders (EMS, health care workers, firefighters, police, congregate care staff).
  • Education staff (teachers, support staff, daycare workers).
  • Food and agriculture workers.
  • Manufacturing workers.
  • Corrections workers.
  • U.S. Postal Service workers
  • Public transit workers.
  • Grocery store workers.

This list could be updated in the future.

After a careful examination of the latest data, and deliberative discussion around booster shots, the updated guidance from CDC follows the FDA’s October 20th amendment of the emergency use authorizations for COVID-19 vaccines to allow for the use of a single booster dose. Those who receive a Moderna booster will get a dose half the amount received during the primary series.

Michiganders should bring their COVID-19 vaccine card or immunization record with them when getting their booster dose, which are available at any vaccine provider that have Pfizer, Moderna or Johnson and Johnson vaccines. Immunization records are available online at the Michigan Immunization Portal for many residents and can be downloaded and printed. To obtain their record, Michiganders must create a MILogin account at and upload a valid government issued photo ID such as a driver's license, state ID or passport. There is no cost to access the portal.

As previously recommended, Michiganders with moderately to severely compromised immune systems should receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of Pfizer-BioNTech COVID-19 or Moderna COVID-19 vaccine. This additional dose is intended to improve the response of people who are immunocompromised to their initial vaccine series.

To date nearly 69%, or two in three Michiganders, have gotten at least their first dose of one of the three safe, effective vaccines. From January to October 12, unvaccinated Michiganders accounted for 93.1% of COVID cases, 90.7% of hospitalizations and 90.5% of deaths.
