His remarks got here simply hours after Rochelle Walensky, director of the Centers for Disease Control and Prevention, informed “Good Morning America” that Delta would possible become the dominant strain in the US in the coming months.

The extra vaccination charges proceed to drop, the extra alternatives there are for Delta to unfold – and due to this fact preserve replicating and mutating.
“The worst-case scenario is if Delta mutates into something completely different, a completely different animal, and then our current vaccines are even less effective or ineffective,” Vivek Cherian, an inner medication doctor in Baltimore, recently told Insider.
