From what I understand, we have data that shows a few people per million have a serious health condition that appears to be similar in order of magnitude as the normal background rate of the same condition without the vaccine. As someone else in this thread said, isn't that (potentially) like someone getting hit by a car, then calling that a side-effect? When dealing with very large numbers of people, there's going to be deaths at all ages due to the normal vagaries of life. Do we have enough information to be certain that these clots are genuinely above the background rate?
