You forgot to account for the fact that the death rate of the vaccine, or deaths per dose, is not the same for every age group. Still, if we assume the vaccine is 50x more likely to kill elderly than children or young adults ( I think it's something like that, I've got the death rates by age saved somewhere), then the vaccine is roughly as dangerous as covid-19. (And if you include vaccine side effects then the vaccine is much worse for children and young adults). Even with the small and underreported numbers it doesn't make sense to get the vaccine.

But like other people said, those current small and likely grossly under reported numbers we have is the least of my concern, the big concern is if in the future the blood clotting, fertility, or other unknown problems are exacerbated by all the people who got the vaccine.
