Yikes. Even as an amateur I can see the problems with the approach taken in the Science Open paper. They tried to do statistical analysis on VAERS entries? The system of self-reporting? And did nothing that I can observe to try to control for the memetic passage of the "covid vaccination causes myocardititis" belief ripping through the international community? That's like claiming that October causes people to be more scared of the dark and completely ignoring the fact that the horror movie marathons run around Halloween.
