Don't see a point here fish. It showed up in the clinical trial, they knew about it and had a measure of it. Plus, that was a different era and was nowhere near as under the microscope of the vaccine roll-out.
Did the clotting show up in the trials of the vaccine? If not, then that's why they suspended it. It was an unexpected result. Any product developer would put a hold status on something that could kill. Well, except auto industry so let's call it, most. I don't think suspending was a mistake or just about law suits. Its good science to at least give it a short pause to see if the problem can be isolated. If not, then they'll add another line to the disclaimer.
