So you also don’t believe the “Not Serious” number of 18,686 means anything, right?
It may mean something. It may mean nothing. The proper use for that data is to model it against known baselines and investigation deviations from normal, based on the studied cohorts. Neither you nor I know whether the events listed are happening at a normal background frequency unless we're actually studying the dataset.
In other words, if between 900 and 1100 people fall and break their hips in a normal January - March timeframe and 975 people fell and broke their hips January - March, then do those falls mean anything? Do they mean the vaccine is causing people to fall down? Should that number be zero suddenly because of the vaccine?
The obvious answer in that example is that the 975 falls likely mean nothing because they're well within the normal range. But some here will trot those numbers out and rant about how 975 people have fallen and people who are pro-vaccine don't even care about the evil vaccine making everyone fall over.
