US top coronavirus adviser 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. "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." Earlier this week, Fauci stated that most COVID-19 vaccines are highly effective against the rapidly spreading Delta variant and reiterated his request for people to get vaccinated as soon as possible. The head of the National Institutes of Allergy and Infectious Diseases also said he is "quite concerned" about the Delta variant in the US.
