WTF are you talking about? Do you even know how to Facebook? You keep replying to me but you’re not actually replying to the thread you’re referring to so I have no worldly idea what you’re even talking about
“Here in the US everyone has a QR code for vacs” is untrue. States that have a digital database or QR code do have that. Some limited clinics may provide you a website (QR) where you can view your vaccination but I’ve never seen that.
I’m not sure what you were trying to say but the way you phrased that would certainly suggest that the US has a QR system (digital database).
The US does not have a federal digital database (QR code) system and never will. At least not a mandatory one. Some states have a digital system but many do not.
As to your second point and question, yes you can go Visa exempt but, you still need a Thailand Pass and that is the point at which you are required to submit proof of vaccination
