It's not a control if it's self-selected.

  Nonsense. If a person is unjabbed, they're in the control group, period.

    Nope. For the control group to be valid, it must be drawn from the same reference class as the treatment. You could of course argue that in all respects that matter for the risk of heart disease, people who take vaccines are the same as people who don't. I would disagree, and only a bet could settle the difference.
