This is the primary reason I am not all that concerned about a Marek's sort of nasty. The "N" part of the protein is well-conserved and, in addition, there is material pre-existing cross-reaction in the population we've known about since Diamond Princess, and known why since last summer on a conclusive scientific basis.

Well, does that change if these fucking ghouls get to an 80% or so vax rate? What is the percentage of non-vaxed we have to keep to have a decent chance of keeping a Marek's scenario as an outlier?

I'm absolutely not trying to beat the fear porn drum; we've had enough of that for the last 18+ months. And no, I don't expect you to have an exact answer for that either, because I don't know if it is a knowable thing.

We're fucked. There will be no happy ending here; there is no going back to 'normal.'. There are only bad outcomes and worse outcomes. And we don't get to choose those, either.
