Dr Anthony Fauci on Sunday (local time) characterised the Delta strain of COVID-19 as a "nasty variant". "It is very clear that this is a nasty variant.
It has a much greater capacity of transmitting from person to person," Fauci said, adding that the COVID vaccines that are being used in America to fight the coronavirus "are working very well" and do protect against the Delta variant. "The bad news is that we have a very nasty variant, the good news is that we have a vaccine that works against it," The Hill quoted Fauci's interview with ABC's "This Week." The nation's leading infectious disease doctor also voiced concern for what he called a "schism between some states and some areas that have a very low level of vaccination." US
