But at this point, the vaccines have been given to, what, billions of people? And the number of people who have suffered severe ramifications that can be attributed to a vaccine rounds to zero. And as far as "Well, we don't know the long-term effects" arguments go... OK, superficially that sounds reasonable. But there isn't, to the best of my knowledge, even a good theoretical explanation of how/why to expect any long-term effects. The vaccine itself is eliminated from your system in a few days if I understand correctly, leaving behind only anti-bodies manufactured by your body.
So yeah, I guess it's possible, in principle, that 3 years from now, or 10 years from now, or whatever, people that took the vaccine could start keeling over spontaneously, or growing third eyeballs in the center of their foreheads or something. But the odds of that happening seem way, way, way beyond even "ludicrously low". To my way of thinking, it "rounds to impossible". So I'd like to know why these folks think differently and apparently expect something bad to happen if they take the vaccine.
