I don't get one thing.
Let's say whole France gets vaccines. They can still get the virus but, as they say, it's less harmful than living without one. But the fact is that they get exposed nevertheless. Right?
So... why do I need a vaccine if I want to travel to France? If I have covid then they still get infected, but yeah, to a lesser degree, so they don't end up in hospitals. So why do I need that covid passport/vaccine shot? France cares about me?
