Completely agree here. Disney isn’t likely to require vaccine.
People and public health policy are different things. Just like people frequently want antibiotics immediately, but policy wants to avoid overuse to prevent resistant strains from developing. People want to be done with mitigation efforts. Public health policy wants to use vaccination to reduce spread and also wants to minimize the frequency vaccinated people are exposed to virus.
If we vaccinate enough people, spread will fall off dramatically, and it’ll all work out. If we don’t, the likelihood of a variant that isn’t protected against goes up. That’s what I expect policy to be based on. Then, businesses to follow policy based on liability exposure. I expect people to be grumpy, just like when they don’t immediately get the antibiotics.
Temp checks are easy, low risk, and screen out active symptoms, even if they miss a lot.
Vaccine documentation validation is hard, risk prone, and misses creates greater liability. People will fake it, thus creating extra liability.
For international travel, customs has the resources to do it. They’re already checking regular passports.
For something like a movie or concert, I wouldn’t trust them to validate a fake.
