That won’t fly in this country. However, the idea of passports is worth considering though. The thing to consider is the charge of involuntary manslaughter. Which sounds a bit over the top, but the act of coming into contact with other people without affording some sort of protection fits that charge pretty much exactly.
a person may fall foul of this simply by causing a death even though he or she did not intend that outcome.
with all the evidence available now, it certainly fits the reckless or criminal negligence part.
For example, I use the same hairdresser as my wife, just because, well I don’t really know why, I just need a short back and sides. However, a few weeks ago the lady was cutting my hair, this subject of vaccinations came up. She proudly said that she will not be having it, and that most of the people in the salon are the same.
Had I know this, I would not have gone. The question arises as to whether, through recklessness, or indeed criminal negligence, on the part of the salon owner or the hairdresser. I it was found that she had COVID and one of her clients caught it from her, would she be liable?
