Excellent observation. When Drosten coded that first PCR test for Covid before Covid was declared, we were in Berlin. I started looking backwards, to see the "run-uop." Unrelated to the so-named pandemic, I came across EU statements looking forward to a "vaccine-styled" travel pass which would be 1) electornic-based like an app, 2) required to prove such things as personage and vaccination history, and 3) various other digitized data. From as early as 2015, during the Obama era here. Ten years later, a little version is being proposed. E-passport visas, with a mind to track individual -- excepting of course those wacky migrants and economic freeloaders.....
This has been an EU Commission "wet dream" for a long time.
