A sturdier spike protein explains the faster spread of coronavirus variants

(Boston Children's Hospital) The fast-spreading UK, South Africa, and Brazil coronavirus variants are raising both concerns and questions about whether COVID-19 vaccines will protect against them. New work led by Bing Chen, PhD, at Boston Children's Hospital analyzed how the structure of the coronavirus spike proteins changes with the D614G mutation -- carried by all three variants -- and showed why these variants are able to sp
