The SARS-CoV-2 spike (S) protein has undergone significant evolution, enhancing both receptor binding and immune evasion. In this review, we summarize ongoing efforts to develop antibodies targeting various epitopes of the S protein, focusing on their neutralization potency, breadth, escape mechanisms. Antibodies receptor-binding site (RBS) typically exhibit high neutralizing potency but are frequently evaded by mutations in variants. contrast, conserved regions, such as S2 stem helix fusion peptide, broader reactivity generally lower potency. However, several broadly have demonstrated exceptional efficacy against emerging variants, including latest omicron subvariants, underscoring potential vulnerable sites RBS-A RBS-D/CR3022. We also highlight public classes different protein. targeted present opportunities for germline-targeting vaccine strategies. Overall, developing escape-resistant, potent effective vaccines remains crucial combating future This review emphasizes importance identifying key utilizing antibody affinity maturation inform therapeutic design.
