The Biden administration is preparing to fast-track authorization of revamped Covid-19 vaccines to combat Omicron as a study from South Africa suggests the fast-spreading variant might cause less severe illness than its predecessors.
Federal regulators on Sunday said cases have been identified in 16 states and that the Food and Drug Administration is already in conversations about streamlining authorization for revamped vaccines. Agency officials have met with vaccine makers and are working to set guidelines for the type of data that will be needed to swiftly evaluate the safety and efficacy of changes to current vaccines.
