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. Originally Posted by Excargodog

Eventually when immunity wanes - naturally acquired or from immunization - it does recur as shingles, which CAN be transmitted to chickenpox susceptible. And shingles occurs in almost one-third of people over the course of their lifetime, sometimes multiple recurrences.https://www.cdc.gov/shingles/surveillance.html

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.

Almost everyone who gets that is immune compromised.
