This is the sort of finding that would normally come out of a stage 3 clinical trial. It's going to be interesting to look back at the effects of these vaccines over the coming years. It's unfortunate that the regulatory trials lost their control groups so early, but it seems unlikely at this point that the control group on a population scale is going to be eliminated.

Hm, not sure. This is a kind of side effect you wouldn't expect and would easily overlook. A proper, very long Stage 3 trial could definitely miss it. Generally women's health issues are often overlooked, especially one that is quite mild. That's why we have Phase 4 trials, amongst other things.
This one is especially difficult to pin down because it's a one off. It's not at all evident that longer phase 3 trials would have caught an event that happens at most a month after vaccination.
