The updated shots are part of a push by public health officials to align the next COVID vaccines more closely with the actual circulating variant of the virus, similar to the way annual flu shots are designed. The U.S. Food and Drug Administration (FDA) on Monday authorized updated COVID vaccines made by Pfizer (PFE.N) and its German partner BioNTech SE (22UAy.DE) as well as by Moderna (MRNA.O). CDC Director Mandy Cohen is expected to approve the recommendations issued by the advisers, allowing Americans to get the updated vaccines. The first COVID vaccines in 2020 were monovalent, or single-target vaccines, aimed at the original strain of the virus. They were followed by bivalent COVID vaccine booster shots that targeted both the original and the Omicron strains.
