Some people apparently are just resistant to it. I still haven't had it, and haven't had a covid vax for a couple of years now. It's been floating around at work on a semi-regular basis so I'm pretty sure I would have been exposed quite a few times.
Dancing on a mountain of bones sounds like a bit of a risky manoeuvre. We survive Covid and die after tripping over a badly placed femur, rolling down the side of the mountain and being crushed under an avalanche of skulls.
Perhaps we can crush the bones and use them to create a nice, flat, hard-packed dancefloor instead?
