FDA Backs Monovalent XBB.1.5 Covid Vaccine
One day after an FDA advisory committee voted 21 to 0 (see story) to recommend that the Covid-19 vaccination program for the 2023-2024 season should contain a monovalent vaccine comprising the XBB-lineage variant, the agency posted a notice that adhered to the panel recommendation.
The 6/16 FDA notice advised manufacturers that they should develop vaccines with a monovalent XBB.1.5 composition. “This recommendation incorporates advisory committee input and is based on the totality of the available evidence to select the vaccine composition that the FDA anticipates will best protect public health,” it says. “The agency anticipates the timely submission of the data and filings to support FDA action on updated Covid-19 vaccines in order to make vaccines available this fall that meet our standards for safety, effectiveness and quality.”
