It's not the stats, it's using VAERS that's the problem.

VAERS is a tip line. It displays every tip it gets, regardless of where it comes from, and doctors HAVE to submit tips if an injury occurred after the vaccine, even if they're reasonably sure that the vaccine didn't cause the injury itself.

VAERS itself says nothing in the numbers it provides is verified. The numbers are used to direct researchers on where they should investigate further. As it stands, the vaccine could be 100% safe, and VAERS would look identical to how it does, because again, it's showing you tips its received, not verified vaccine injuries.

A report to VAERS generally does not prove that the identified vaccine(s) caused the adverse event described. It only confirms that the reported event occurred sometime after vaccine was given. No proof that the event was caused by the vaccine is required in order for VAERS to accept the report. VAERS accepts all reports without judging whether the event was caused by the vaccine.

If you want data on vaccine injuries, VAERS is not going to offer you any proof that will convince anyone on the other side, because again, it's a tip line, not a database of verified vaccine problems.
