A new VOC termed omicron (PANGO lineage B.1.1.529) has recently emerged in South Africa and has since then spread worldwide. A major feature of this VOC is the high number of mutations into the Spike (S) protein, much higher than any other VOC. In this study we investigate the effects of those mutations and how they apparently modulate the affinity...
