The Omicron BA.2.86 subvariant differs from previous variants by over 30 spike mutations. Here, the authors report that BA.2.86 likely evolved in Southern Africa and that its immune escape is not larger than recently circulating SARS-CoV-2 strains. Neither its replication nor its pathogenicity are enhanced in vitro.
