Somehow I never heard anyone complain that there were required vaccinations for faraway countries. Only when refusing an important vaccination became a symbol of <fill in the blank> did those in question start to argue nobody should be asking if they're a danger to themselves[1] and each other[2] because that's "private" "medical" information.

And in case you did get vaccinated or cannot for medical reasons, but just truly believe this info is a private thing, not sure why you would suggest that the question is not allowed to be asked. People can decide for themselves to answer or not, right?
