As i said in other threads -> The immunity passport is just a PR stunt by the airline, travel industry and some authoritarian governments.
All it takes is some "bad apples" -> clinics, doctors, vaccination centers -> where they will put you as being vaccinated into the database, if you give them USD 100, without giving you the shot; The "bad apple" would then also state that the vaccine id had been administered; In reality this shot is resold via some dark channels to some poor countries, where people pay good money to receive the vaccine; Yes, this may not happen in the UK or Germany, but the world is bigger than that.
Mr Tehan said Australia wants to work with Singapore on developing a digital vaccine passport that will prove that a traveller has been vaccinated. "We really want that digital vaccination passport up and running, operating, and in a way that we know that we can trust it," he said.
Hahaha, this is a nice wish, but a digital vaccination passport can never be trustful.
We are already seeing lots of corruption in the Covid system;
You can buy a negative PCR-Test on the street;
And if you don't pay extra for the PCR-Test, the test center will just issue a false positive test-result, which will land you into much trouble;
so the deal is -> USD 200 for a negative test result; USD 50 for a positive test results;
