I meant to clarify that in iceland it effectively means you can leave and come back in if you are Icelandic not that we can go there if vaccinated. I do think individual countries will end up with a similar rule. But in some cases go further and say you can’t go to certain other countries unless you have it.[/quote]
You can leave and come back anyway, though (and you can come from many countries as well). It just means you don't have to do the quarantine when you return (you'd still have to do it in the destination country if they didn't have the same system - I don't know if anyone does).
I appreciate that for many people the quarantines make travel impossible regardless of restrictions but travel restrictions and quarantine requirements are different parts of the equation.
I thought that when people talked about vaccine passports they meant a system where people would not be able to travel internationally without one.
