摘　　要：Coronavirus disease 2019(COviD-19)was first reported three years ago,when a group of individuals were infected with the original SARS-CoV-2 strain,based on which vaccines were developed.Here,we develop six human monoclonal antibodies(mAbs)from two elite convalescents in Wuhan and show that these mAbs recognize diverse epitopes on the receptor binding domain(RBD)and can inhibit the infection of SARS-CoV-2 original strain and variants of concern(VOCs)to varying degrees,including Omicron strains XBB and XBB.
