@phl43 From what I can tell from smart epis, I think the issue is that B.1.1.7 and B.1.357 aren't necessarily in the same bucket. B.1.1.7 seems to be intrinsically more transmissible in non-immune people. B.1.357 may or may not be and its advantage may come from partial immune escape. — PolitiTweet.org
