An outbreak involving a variant with 484K in a vulnerable vaccinated population still showed *very* strong (86.5%) protection against symptomatic illness. This is *very* good news, and should build further confidence in vaccinationhttps://www.cdc.gov/mmwr/volumes/70/wr/mm7017e2.htm?s_cid=mm7017e2_w …

Yes, encouraging how well things are holding up even in worse case scenarios—already vulnerable population AND congregate living PLUS a variant that had caused a lot of worry. Better than I hoped. I mean, OC43 outbreaks cause deaths in nursing homes... This is solid protection.

Except this wasn’t one of the variants that had caused a lot of worry. “In the Kentucky outbreak, the virus variant is not on the C.D.C.’s list of those considered variants of concern or interest.”

It's not on the official list, yet, but it has E484K. There is a lot of convergent evolution going on so we are seeing the same mutations all around.
