With coronavirus on the upswing, new vaccine coming (ever so slightly) sooner than expected
The U.S. Food and Drug Administration said this year’s updated version of the COVID-19 vaccine is likely to come out by the middle of next month, a bit earlier than the late September timeline previously announced by the Department of Health and Human Services.
The earlier-than-expected arrival became apparent after the U.S. Centers for Disease Control and Prevention scheduled a Sept. 12 meeting of its Advisory Committee on Immunization Practices, a likely indication that the vaccine would become available shortly afterward.
The latest version of the vaccine is designed against the Omicron subvariant XBB.1.5, unofficially known as #Kraken.
Unlike last year’s formulation, a bivalent vaccine that was designed against both the ancestral coronavirus strain and the BA.5/BA.4 Omicron subvariants that were circulating at the time, the upcoming vaccine will be #monovalent, specifically designed against #XBB.1.5.
