Here, we investigated the extent of such escape in nine convalescent patients infected with the wild-type SARS-CoV-2 during the first wave of the pandemic. Among the total of 476 monoclonal antibodies (mAbs) isolated from peripheral memory B cells, we identified seven mAbs with broad neutralizing activity to all variants tested, including various omicron subvariants. Biochemical and structural analysis indicated the majority of these mAbs bound to the receptor-binding domain, mimicked the receptor ACE2 and were able to accommodate or inadvertently improve recognition of omicron substitutions. Passive delivery of representative antibodies protected K18-hACE2 mice from infection with omicron and beta SARS-CoV-2. A deeper understanding of how the memory B cells that produce these antibodies could be selectively boosted or recalled can augment antibody immunity against SARS-CoV-2 variants. Infection with wild-type SARS-CoV-2 elicits broadly neutralizing and protective antibodies against omicron subvariants.,Ju B, Zhang Q, Wang Z, Aw ZQ, Chen P, Zhou B, Wang R, Ge X, Lv Q, Cheng L, Zhang R, Wong YH, Chen H, Wang H, Shan S, Liao X, Shi X, Liu L, Chu JJH, Wang X, Zhang Z, Zhang L Nat Immunol. 2023 Apr;24(4):690-699. doi: 10.1038/s41590-023-01449-6.
