This study found that more people had heart issues following a covid diagnosis vs. following a vaccine dose. The thing is, the majority of people are vaccinated and therefore can be in both groups--the study has no way of separating.
It therefore doesn't actually follow that the vaccine causes less harm. As a matter of fact, since the vast majority of people who had heart issues following covid have had at least one dose, only two things can follow:
-the vaccine failed to prevent this outcome
-or the vaccine made this outcome more likely
In other words, the best case scenario is that you have a risk of getting a heart condition from covid regardless of whether you're vaccinated. Then, getting vaccinated simply adds a separate additional risk.
Worst case scenario, the vaccine makes the heart condition more likely when you get covid.
