"As promised, U.S. health officials are devising a plan to update the booster vaccine for the fall to better protect against emerging variants of the coronavirus. The rationale for this new formulation is strong — especially if it’s targeted for high-risk Americans.

Advisers to the Food and Drug Administration voted unanimously this month in favor of the updated shot. Instead of the bivalent booster, which targets both the original coronavirus strain as well as two omicron subvariants (BA. 4 and BA. 5), the updated one will be specific to just one variant: the omicron offshoot XBB.1.5.

This is the right call. The Centers for Disease Control and Prevention reports that XBB subvariants constitute more than 95 percent of the circulating variants. While XBB.1.5 is on the decline, two other XBB derivatives are accelerating. Federal health officials project that XBB.1.16 will be dominant by the fall and other sub-lineages such as XBB.2.3 will increase in proportion."
