The US border is a bit of a dilemma. It looks like the Canadian government is co-operating with the EU concerning the EU's "digital green certificate", and it's pretty likely that many other countries will join that, too - but it doesn't look like the USA will be one of them. What happens when a resident of the USA wants to travel to Europe? Or go on a cruise? Some of the cruise line companies have been talking about wanting proof of vaccination. The IATA (International Air Travel Association) has been talking about doing their own. I sure hope the IATA co-operates with the EU, and at least makes the two systems talk to each other, if not simply accept the EU's documentation as-is. (I really hope it ends up with ONE system accepted worldwide ... be it the EU's system or something else ... but, ONE system worldwide.)
As far as JT stating the border not re-opening until Canada is 75% vaccinated (whatever that means), this may be a negotiating tactic to gently prod the USA into doing something better than an easily-forged piece of paper as proof of vaccination. It may morph into "We'll open the border to Americans who can demonstrate proof of vaccination or test results showing that they are not infected" ... like that digital green certificate ...
As for various US Republican state governments "banning vaccine passports" ... that's only going to work internally. It won't help when you arrive at the Lufthansa gate in O'Hare Airport and the gate officer asks for your covid19 documentation before boarding. If you get past that - It won't help when you arrive at passport control in Munich and EU border control asks for your documentation. Where that gets really interesting is when the US resident needs to prove their vaccination status using information obtained from said US Republican state government ... "Oh, we don't keep track of that. You're on your own." Passport control in Germany ... "How nice. Back you go. Not our problem that your government is incompetent."
