I kinda dislike what the WHO has done with Omicron though. It has had so many lineage variants over the past year that we should have had 4-5 official new named variants by this point, but they seem to be avoiding doing that for some reason.
So we're dealing with unofficial sub-names now with the currently rising Eris variant and the emerging Pirola variant.
They are so genetically different from Omicron at this point that they make Omicron look like the same lineage as Delta.
So, yeah, it's been aggravating me that they haven't been officially recognizing these still ongoing pandemic variants.
