NBC News (5/28, Lovelace Jr.) reports that the FDA’s Vaccines and Related Biological Products Advisory Committee “on Thursday recommended updating this fall’s Covid shots to target the XFG variant.” NBC News adds, “XFG is a hybrid of two omicron variants and carries mutations that could help it partially dodge antibodies, Natalie Thornburg, who leads the CDC’s respiratory division, told the panel.” CDC data indicated that “as of May 8, XFG and its descendants account for more than half of new infections in the U.S.”
