Medical Professionals Reference (MPR)FDA: Use Bivalent COVID-19 Vaccines; Monovalent Ones No Longer Authorized

The FDA has authorized the use of the mRNA bivalent COVID-19 vaccine (Moderna and Pfizer-BioNTech) for all doses administered to individuals 6 months of age and older. The monovalent vaccines are no longer authorized for use in the US. This simplifies the vaccination schedule and encourages future vaccination. For child vaccination, unvaccinated children may receive a 2-dose series of the Moderna bivalent vaccine (6 months through 5 years) or a 3-dose series of the Pfizer-BioNTech bivalent vaccine (6 months through 4 years). Children who are 5 years old may receive 2 doses of Moderna bivalent vaccine or a single dose of Pfizer-BioNTech bivalent vaccine.

For immunocompromised children 6 months through 4 years, eligibility depends on the vaccine previously received. For individuals 5 years of age and older with certain kinds of immunocompromise, a single additional dose of bivalent vaccine may be administered at least 2 months following the initial dose of a bivalent vaccine. Additional doses may be administered at the discretion of the health care provider, taking into consideration the individual’s clinical circumstances.
