About the new variant? well, it is early days 7 the new variant was discovered just 3 days ago. genetic analysis shows it has twice the number of mutations as delta, the dominant variant worldwide, including around 30 changes to the spike protein which the virus uses to break into human cells. this makes it dramatically different from the original wuhan strain on which all current vaccines are based. crucially there is no evidence yet that the variant causes more severe disease or that it makes vaccines less effective. it will take two to three weeks before laboratory tests can show whether th...

On their immunizations, and if you're not immunized, this should hopefully be another wake-up call and reminder. >> i'm going to get in trouble because we're out of time, but i want to ask you, dr. fauci kind of hedged a little bit. he said there's no indication that it is here. but when i talked to dr. hotez last hour, he said, kind of what you were indicating, like, it wouldn't surprise him at all if it is, indeed here. and his correspond is that we're not really good as a country for testing for this kind of thing. it isn't a regular part of what we do. and when we talk about what the u.s. ...
