that's what worries me the most with the medical passport that soon will be required everywhere just to go see a concert : now that it's there, it's never going to stop, it can only expand.
not only because the virus is very likely to follow the same path as the flu, and so people will need yearly vaccination with mediocre results, but also because politics will use this as a hammer and see nails everywhere.
On a sidenote, a 100€ / year vaccine every year, for 6 billions people, enforced by laws... sounds like a dream business model...
