Bivalent Pfizer and Moderna COVID-19 vaccine boosters authorized for children ages 5 years and older

To continue fighting the COVID-19 omicron variant, the U.S. Food and Drug Administration has amended an Emergency Use Authorization for bivalent COVID-19 vaccine for booster doses to include children starting at five years of age. The bivalent boosters are authorized for administration at least two months following completion of primary or booster vaccination in adults and children over the age of five years. 

Individuals may choose to receive either the Pfizer or Moderna bivalent booster, regardless of which primary series vaccine or original booster dose they had previously. Influenza vaccines, which are now available in Michigan, can also be co-administered with the COVID-19 bivalent booster doses.

“This is great news for children in Michigan as we head into the fall and winter, when we expect cases of seasonal respiratory viruses, including COVID-19, to increase,” said Dr. Natasha Bagdasarian, Michigan Department of Health and Human Services (MDHHS) chief medical executive. “The bivalent booster will help fight the omicron subvariants, which are predominately circulating around the state. COVID-19 vaccines remain our best defense against the virus, and we recommend all Michiganders stay up-to-date.”

The Moderna and Pfizer bivalent boosters target two strains of COVID-19 – the original strain of the virus and the currently circulating omicron variants (BA.4 and BA.5). Individuals ages 5 years and older who have completed any FDA-approved or -authorized monovalent primary series (Pfizer, Moderna, Novavax or Johnson & Johnson) or previously received monovalent booster doses are eligible to receive one age-appropriate bivalent (Pfizer for those aged five years and up; or Moderna for those aged six years and up) COVID-19 booster. 

All eligible Michiganders can receive the bivalent vaccines, which are currently available at vaccine providers across the state. To find a vaccine near you visit Monovalent COVID-19 boosters are not authorized as booster doses for persons 5 years and older.

To date, over 6.8 million Michiganders ages 6 months and up have gotten at least their first dose of safe and effective COVID-19 vaccines. Eligible Michiganders are encouraged to stay up-to-date on vaccinations, which includes booster doses that provide extra protection. Persons who live or work in settings where COVID-19 outbreaks can spread quickly (like long term care facilities) are especially encouraged to stay up-to-date

MDHHS also encourages Michigan residents to pay attention to local guidance as some communities may be at a higher risk of COVID-19 transmission.
