> Are unvaccinated with no previous infection and unvaccinated with natural immunity split out into separate categories?

Yes it the latter can prove via PCR test at the time of infection. Anecdotes don’t count

> Are the vaccinated actually still fully vaxxed or are they MONTHS past when their protection is gone and they're still counted as vaccinated?

Yes, it is on the individual to stay on top of things according to their own risk calculus. Vaccines protect the individual. As a thrice vaxxed person I don’t really care if everyone around me is not vaxxed.

> Are post-vaccine deaths due to Myocarditis for example being counted as unvaccinated because they haven't reached the 14 day park post-vaccination?

One of the problems I’ve had with our covid death counts has been counting people who has covid and died as died due to covid. I would be a hypocrite if I said we needed to be that loose with vaccine deaths
