USA already has these in the works. Two weeks ago I got my official certified copy of my Covid-19 vaccine certificate from the CDC database. It’s an 8x11 page with a seal on it and the date of my vaccination, the manufacturer and lot number, and the location. Oh, and my home address.
I’m traveling in Europe and needed it to enter France and to stay in a hotels. It’s the first thing they ask for in Paris, even before my passport. In Austria and Hungary they did not ask for it and virtually no one wears masks.
It took me 15 calls to find out how to get it. They are available online once you find the portal. I suspect law enforcement and the Biden doorknockers have this in the laptops.
We got a CDC Vaccination card when we got vaccinated. Not sure if that is enough or whether we need this certificate. We are going to France in September.
