>The other one to watch is the segue from mortality to positive test. Of note is that society never used to test vaccinated people in the old days when the goal was herd immunity, so there's not much precedent as to what a positive test after vaccination might actually mean. The best known example probably would be TB, where a post-vaccination Mantoux test would be expected to be positive, though that's a different sort of test.

Ours were still positive at age of 47.
