With regards to the side effects that don't matter (feeling really tired for one or two days) they're stronger than the average flu shot, so maybe they're stronger in other ways, or maybe not. Nobody can quantify the reporting bias on VAERS, and the side effects of midrange severity showing up there aren't scary enough to justify the kind of regulatory investigation that the blood clotting thing received, so we are unlikely to see a study on this in the near term.
