An abstract published by the American Heart Association suggests a correlation between mRNA vaccines and heart disease.

They even featured it on November 13th at their AHA Scientific Session 2021.

The problem is there is no evidence. I don't mean "no evidence" as in it is just correlation, the kind of bad correlation Harvard School of Public Health trots out every month using food frequency questionnaires to link a health benefit to some new fad, I mean no evidence. None. It is just an abstract. And called out for being pretty bad at that.
