The SARS-CoV-2 spike(S)protein engages ACE2 for cell entry,and the S protein/ACE2 interface is an important target for neutralizing *** the course of the COVID-19 pandemic,SARS-CoV-2 variants have emerged that harbor mutations in the S protein,which confer neutralization resistance and allow viral spread in immunologically nonnaive *** most prominent example is the highly mutated Omicron variant,which infects convalescent or vaccinated individuals with unprecedented efficiency[1,2].
