Here, a panel of human nAbs from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) convalescent patients show diverse neutralization against Omicron, of which XMA01 and XMA04 maintain nanomolar affinities and excellent neutralization (half maximal inhibitory concentration [IC50]: approximately 20 ng/mL). nAb XMA09 shows weak but unattenuated neutralization against all variants of concern (VOCs) as well as SARS-CoV. Structural analysis reveals that the above three antibodies could synergistically bind to the receptor-binding domains (RBDs) of both wild-type and Omicron spikes and defines the critical determinants for nAb-mediated broad neutralizations. Three nAbs confer synergistic neutralization against Omicron, resulting from the inter-antibody interaction between XMA04 and XMA01(or XMA09). Furthermore, the XMA01/XMA04 cocktail provides synergistic protection against Beta and Omicron variant infections in hamsters. In summary, our results provide insights for the rational design of antibody cocktail therapeutics or universal vaccines against Omicron. Three SARS-CoV-2 antibodies provide broad and synergistic neutralization against variants of concern, including Omicron.,Wang S, Sun H, Zhang Y, Yuan L, Wang Y, Zhang T, Wang S, Zhang J, Yu H, Xiong H, Tang Z, Liu L, Huang Y, Chen X, Li T, Ying D, Liu C, Chen Z, Yuan Q, Zhang J, Cheng T, Li S, Guan Y, Zheng Q, Zheng Z, Xia N Cell Rep. 2022 May 24;39(8):110862. doi: 10.1016/j.celrep.2022.110862.
