mate these passports like the one in israel expire months after the you take the last shot, after which you have to get the shot again or lose your freedom, I'm not even making this up it's literally the rules
that's a total lie, how would they know you have a year immunity if they havent even had these vaccines for a year, why would the CDC have it this way then
CDC for example, the freedoms you are given last 3 months from your shot, after then you have the same freedom as someone unvaccinated, Israel's vaccine passport is also time limited as well
Also it is well accepted that the vaccines last 3 months before you need a booster (this is why the CDC let you skip quarantine if your in contact within 3 months of vaccinates) so dont rule out the fact you'll have to get it again closer to the time if the rule changes
