@Neonsignal - Doesn't matter when you get down to it. The mRNA is taken up systemically so where the spike is produced will be "everywhere." Whether it then gets released and circulates everywhere or whether it stays where it's produced everywhere is everywhere, and there's little or no difference of substance.

Given the apparent secondary contact-level expression of pathology from people vaccinated to those who have not been, however, I suspect the claim that the spike produced never leaves the original cell that takes up the mRNA is flat-out bullshit. I don't have the lab equipment to prove it, but it wouldn't be hard to prove in someone newly-vaccinated; wait 2 days and then see if you can find the spike protein in the blood. Given the anecdotal reports I'd put a big steak dinner wager on that one. Oh, and at least one of the trial documents for these mRNA shots discloses the potential for environmental secondary exposure, so it is NOT something the manufacturer didn't think of.
