More cardiac issues than the other vaccine options but far less than the virus. If it were the only option it would still be on the market. It was only pulled because better options showed up.
Unfortunately, this isn't a claim that can be made. We don't know how many people got the virus, or how many times. And IIRC, the cardiac issues of the virus were mostly in older demographics, the J&J was affecting young a healthy people.

I have a friend who got Type 1 diabetes after Covid attacked his pancreas. (And he got infected in March 2020, so this isn't someone choosing to be diseased getting their just desserts.)
