So your PCR score indicates you've had the shot and you're immune to the strain you've had. And that means nothing really. You can still catch and transmit other strains. So sure it tells people they won't die of X but Y and Z are still on the table. So are A, B and C. (again according to Fauci)

Also. Uniform? Countries can't agree on how they present dates and numbers. 1.000,00. How many meetings would it take to agree on a Uniform passport that would work internationally. How much would it cost to set up a commission to sort that out.

What about fake passports? Would there be a database? Who would build that? Who would be able to add to it? What security measure would be in place to protect the private medical data of the people?

How much would it cost?

Now given the cost (lets get real millions upon millions) and that the eventual document would be nearly worthless (because of strains). I'm a solid nope on this..

Much better use of tax dollars. Make masks with American flags on them. (or country of your choice). Print these by the millions, and give them out for free.
