The spike protein of SARS-CoV-2 is the target of antibodies in convalescent and vaccine sera,and 23 mutations in spike protein were reported in the variants B.1.1.7,B.1.351,and P.1(Fig.1a).Recently,several groups eval...The spike protein of SARS-CoV-2 is the target of antibodies in convalescent and vaccine sera,and 23 mutations in spike protein were reported in the variants B.1.1.7,B.1.351,and P.1(Fig.1a).Recently,several groups evaluated the effects of convalescent and mRNA vaccine sera on two major circulating SARS-CoV-2 variants B.1.1.7 and B.1.351(Fig.1b),1,2,3,4,5 which leads to concerns about the immune escape of these variants from the human acquired immunity stimulated by previous infections and mRNA vaccines.展开更多
