How about it’s something that arises from the 2nd or later exposure to covid independent of vaccination status? Countries state that some amazing percentage of their populations have had covid and pretty much everybody is ignoring it…

Might also have something to do with the difficulty of getting non covid access to health care, the disruption of peoples lives due to covid or even the huge reduction in exercise due to covid and wfh. Or even boomers and others taking early out and discovering psychological issues with giving up their career.

Or it’s anti-vax.
