The reported adverse reactions are very serious and only occurred after the vaccine a lot of times in an otherwise healthy individual.
It should be used as a canary of safety and each report should be evaluated to see if the vaccine is the causation, especially when the individual was healthy.
Ignoring reports of adverse reactions is not proper science. Sure, we could dismiss ALL of the reports as coincidences, but is that right?
VAERS also states the data is under-reported, because not all side effects are reported to VAERS. This means for all false reports there could be true side effects not reported, this evens out the cases to some extent.
> You could get the vaccine, and then days later, you get diarrhea, or a headache, or a charlie horse in your calf,
Look at the side effects listed, it's full paralysis, death, miscarriages, etc. These are serious events that should be looked into. Those are much more rare cases than a "headache", or "diarrhea". Headaches are not reported to VAERS.
