FDA Advisers Recommend Updating Covid Shots for Omicron XBB.1.5 in Fall.
TL;DR
The FDA has recommended that Covid vaccine manufacturers develop single-strain shots for the fall that target the omicron subvariant XBB.1.5, which is the dominant strain of the virus in the US. The XBB.1.5 strain is a descendant of the omicron variant and is one of the most immune-evasive strains to date. Pfizer, Moderna, and Novavax have already been developing updated versions of their shots that target XBB.1.5, with Pfizer saying it will be able to deliver a monovalent shot targeting XBB.1.5 by July. The updated vaccines could be available to the public around September.
