I got the Moderna vaccines. (3 in 3 years) I have been vaccinated for almost every disease known to man, so I'm not worried about this one. I'm considered to be in excellent health with a low BP, etc.
My GF fell for the fear that was instilled by the media. Getting Covid was a death sentence, according to them and we both got very sick in Feb 2020. It was a bad flu and really tough on her.
I think it would be impossible to qualify something that didn't happen (not getting the vaccine and not dying, versus getting the vaccine and then not getting Covid).
I think there was SOME positive to the vax, but who knows? Maybe it was all a big lie.
