As had been said several times before, vaccination passports aren’t new.
I came across my old vaccination record the other week (passport sized pale yellow booklet): smallpox, cholera, yellow fever, typhoid, and another I’ve forgotten.
Had to show this before you could gain entry to many other countries. Not vaccinated = no entry.
Not a medical record; just vaccinations.
Yeah the difference is you have a CHOICE if you want to go to a country that has those vaccination requirements and you don't want to get vaccinated. It is not the same as if you need to buy groceries, or fly domestically. A vaccination passport in the domestic sense will see riots and protests.
Speaking of riots and protests - I haven't seen any riots or protests in the UK with groups chanting "END THE FREEDOMS - BRING BACK THE LOCKDOWNS" .....
