Also worryingly, it has a large constellation of mutations relative to earlier published sequences of SARS-CoV-2 (the "parental" variant), more numerous than any variant noted before that has been able to expand noticeably.
Some of these mutations are associated with the ability to partially evade antibody responses that have been induced by the parental variant or vaccines. This immediately drew notice. Many countries, including the UK,...
