SARS-CoV-2 variants of concern such as the Omicron variant pose a challenge for vaccination and antibody immunotherapy. Here, Zhou et al. isolate a broadly neutralizing antibody (bNAb), named ZCB11, that protects Golden Syrian hamsters against Omicron. Applying CryoEM the authors show that ZCB11 heavy chain predominantly interacts with RBD in up confirmation, which interferes with ACE2 receptor binding.
