Despite the media clickbait about #SubcladeK being a #SuperFlu or "lethal", there's no evidence that it produces worse symptoms than typical #influenza variants, or even that it's more virulent. Instead we have a combination of a mutation which makes it better at avoiding this year's #flu #vaccine, along with…

wait for it…

lower #vaccination rates.

The vaccine still reduces hospitalization and death rates for subclade K, so it seems likely this year's increase in flu hospitalizations and deaths will be far better explained by the lower vaccination rates (in some countries) plus the early start of the flu season (in some countries) than by the mutation.
