and although zostavax is 50% efficacious and two shots of shingrix are 90% efficacious, nobody mandates that anyone get them and immunization rates even in the elderly are only about 35% in the Anglo population, much less in Hispanics and Blacks. Yet nobody seems to be going in high dudgeon about it, even though it can be a serious disease.
Yes I know all that, and it's neither here nor there. My reference (if your read it) was for kids. Senior citizens don't usually get asked to show chickenpox immunity before they go to daycare, summer camp, etc.
Seniors would reasonably NOT be granted an immunity passport based on childhood chickenpox infection. But since seniors don't tend to spread it to other seniors (or anyone else), it's a moot point. Kids on the other hand do spread chickenpox so immunity status matters.
