New coronavirus variant in New York spurs caution, concern

“I’ve never been more optimistic in the recent past as I am now,” said Andrew Noymer, associate professor of public health at the University of California, Irvine. “The worst variant hasn’t arrived yet … And the way we keep that new variant from emerging is to vaccinate as many people as we can as quickly as we can, because these variants emerge when the old virus infects someone and a new variant comes out. So if we can block that first step through vaccination, that’s the best way to fight the variants. Vaccination is key.”
