'The worst version' of COVID is spreading. Can we update our vaccines in time?
"Experts say BA.5 is the one to worry about: “The worst version of the virus that we’ve seen,” as Dr. Eric Topol, the founder of Scripps Research Translational Institute , recently put it. Together, the closely related BA.4 and BA.5 now account for the majority of new U.S. COVID cases, according to the latest data from the Centers for Disease Control and Prevention — but BA.5 (36.6%) is spreading a lot faster than BA.4 (15.7%). By early July, it will be the dominant strain in the U.S."
