COVID-19 Vaccine Bivalent Update
Posted Sept. 26, 2022
Johns Hopkins Medicine has the bivalent COVID-19 booster.
As of Sept. 2, 2022, the CDC recommends a bivalent (containing components of both the original strain of the SARS-CoV-2 virus and the omicron variant of the virus) COVID-19 booster for people aged 12 years and older (Pfizer) or 18 years and older (Moderna). The bivalent vaccines, which offer better protection against COVID-19 caused by the omicron variant than the earlier, monovalent vaccines, have been authorized for use as a single booster dose administered at least two months after primary or booster vaccination. The monovalent COVID-19 vaccines will no longer be available for booster doses in patients over the age of 12. However, the monovalent vaccines will remain available for the primary vaccine series in all patients and for booster doses in patients younger than 12 years old.
