I have been looking at this "new variant" of the virus which causes COVID-19 and the British Medical Journal has said
What do we know about this new SARS-CoV-2 variant?
It’s been snappily named VUI-202012/01 (the first “Variant Under Investigation” in December 2020) and is defined by a set of 17 changes or mutations. One of the most significant is an N501Y mutation in the spike protein that the virus uses to bind to the human ACE2 receptor (Wise, 2020).
Yet, The University of Sheffield (2020) pointed out that there was a virulent "new strain" (G614 vs D614) identified sometime before July. Is this the same variant but renamed to VUI-202012/01 or am I confused?
