I hope this thread does not trend the wrong way (not a good start) but I was reading that many airlines, vacation spots, and countries may soon require a proof of vaccinations. Talking last night with friends, I was thinking this would be no different than to travel to some places, Angola for example, required a malaria vaccination to get a visa. Does anyone know how such a thing would work while protecting medical (and even to some degree religious) privacy? I'd also guess this will be easier to enforce across borders but hard for say Delta to enforce on a domestic flight. What are your thoughts?
