The emergence of Omicron and subvariants of SARS-CoV-2 illustrates the limitations of solely targeting the receptor-binding domain (RBD) of the spike (S) protein. Here, we isolated a large panel of broadly neutralizing antibodies (bnAbs) from SARS-CoV-2 recovered-vaccinated donors, which targets a conserved S2 region in the betacoronavirus spike fusion machinery. Select bnAbs showed broad in vivo protection against all three deadly betacoronaviruses, SARS-CoV-1, SARS-CoV-2, and MERS-CoV, which have spilled over into humans in the past two decades. Structural studies of these bnAbs delineated the molecular basis for their broad reactivity and revealed common antibody features targetable by broad vaccination strategies. These bnAbs provide new insights and opportunities for antibody-based interventions and for developing pan-betacoronavirus vaccines. Broadly neutralizing anti-S2 antibodies protect against all three human betacoronaviruses that cause deadly disease.,Zhou P, Song G, Liu H, Yuan M, He WT, Beutler N, Zhu X, Tse LV, Martinez DR, Schafer A, Anzanello F, Yong P, Peng L, Dueker K, Musharrafieh R, Callaghan S, Capozzola T, Limbo O, Parren M, Garcia E, Rawlings SA, Smith DM, Nemazee D, Jardine JG, Safonova Y, Briney B, Rogers TF, Wilson IA, Baric RS, Gralinski LE, Burton DR, Andrabi R Immunity. 2023 Mar 14;56(3):669-686.e7. doi: 10.1016/j.immuni.2023.02.005.
