These seem to be touted as the answer to getting sporting events and spectators, flights, holidays going again. All the things we took for granted 12 months ago.
I think it was Qantas that started it rolling by saying they wouldn't fly anyone who couldn't prove they had been vaccinated. You could show your certificate, QR code on your mobile or whatever.
Certainly the UK has shown interest and Ursula said the EU would define the requirements for the Common Pass by the end of January ( been and gone and no definition). The Common Pass would "allow travel and access to open spaces". On the face of it, in everyones interests. Gets the economy going again, holidays, travel and so on. I won't post links as there is plenty of stuff available on google.
My personal view is it is a giant ponzi scheme in as much as it is just a tool to help in the drive to get as many folk vaccinated as possible to reduce health problems. ( if you get it and lower chance of giving it to others). The acid test , in my view , is when someone challenges the legality of it. For example having made bookings and turn up for expensive foreign travel and one or more of the party are refused on a technicality. Or they couldn't have the vaccine because of a medical condition or they might have been an anti vaxer . Or you want to go to a country that doesn't accept the AZ jab for over 65's or you didn't have your second jab within 12 weeks. Same if someone is refused a job or not considered because of their Common Pass status. My gut feeling is that these wouldn't stand up in a court of law. It will be something to do with the Geneva Convention of Human Rights. But that is all some months maybe a year down the line.
What do you think?
