clackeI haven't been keeping up with this, but apparently people were initially very worried about this BA.2.86, a descendant of BA.2 which I seem to remember contributed to one of the waves here and which is itself an Omicron descendant.
However, BA.2.86 turned out milder than feared in practice and instead it seems a strain called EG.5 is a major driving strain. Existing serums and coming vaccines seem to be covering the latest strains relatively well.
