Question: What is a bivalent vaccine?
Answer: Also referred to as an “updated booster,” the FDA-authorized Moderna COVID-19 Vaccine, Bivalent and Pfizer-BioNTech COVID-19 Vaccine, Bivalent boosters include:
- An mRNA component of the original strain that provides an immune response that is broadly protective against COVID-19.
- An mRNA component in common between the omicron variant BA.4 and BA.5 lineages to provide better protection against COVID-19 caused by the omicron variant.
According to the FDA, the BA.4 and BA.5 lineages of the Omicron variant are currently causing most cases of COVID-19 in the U.S. and are predicted to circulate this fall and winter. In June, the agency’s Vaccines and Related Biological Products Advisory Committee voted overwhelmingly to include an omicron component in COVID-19 booster vaccines.
