None of this matters because we have hippa laws that prohibit anyone from asking you to reveal medical information.
I am sure that will not apply to vaccine passports, if they are implemented. There is no way the CDC rules for cruise ships and airplanes will be implemented if authorized employees cannot demand to see your vaccine passport.
HIPPA laws do not prevent officials, airline employees and others from seeing medical information now, today, on real passports. Passports have vaccine information in them. (Or they used to, anyway -- maybe it is separate document nowadays?) You could not travel to Japan or India without proof of various vaccinations. Airline employees would demand you show these documents before they let you on the plane. Customs officials would demand them when you got off.
Primary school officials demand proof that your child is vaccinated. They are authorized. HIPPA laws do not apply. So I am confident that university officials will also be authorized to demand proof.
Ah ha. Here is an article about the situation at Cornell. Quote:
"Schools and colleges have long required proof of vaccination for diseases such as measles and mumps. . . .
And, though the vaccine is new and, so far, has only emergency use authorization from the Food and Drug Administration, Cornell has decided to mandate it for students. "We have consulted legally about this, and we feel it's defendable and appropriate," [an administrator] says.
Some other institutions are holding off on deciding whether to mandate the vaccine until the FDA grants full approval. . . .
I don't recall that Cornell demanded vaccination proofs 1970s, but primary schools sure did, for things like smallpox.
What Cornell demanded was that you could swim 4 lengths of an olympic pool without stopping or touching the bottom. Naked. They still do. I guess it makes sense for a university high above Cayuga's waters, but I don't get why you can't wear a swimsuit. I recall stories of people who dropped out rather than learn to swim. (It was not onerous. I am a terrible swimmer, but I passed with no trouble.)
