"COVID-19 vaccine guidelines and boosters simplified and updated in the U.S."

The Ohio Department of Health has repealed authorization for the monovalent COVID-19 vaccines from Moderna and Pfizer, which were the most commonly administered vaccines at the start of the pandemic. The updated bivalent boosters have shown to provide broader protection against COVID-19 illness, including increased period of protection from severe illness, hospitalizations, and/or death. Monovalent Novavax and Johnson & Johnson/Janssen COVID-19 vaccines can still be administered under the newly updated guidelines. The Ohio Department of Health also provided guidelines for vaccinations with the bivalent Moderna and Pfizer COVID-19 vaccines.
