VAERS was never trustworthy as a raw data source, only as a source of information on what to investigate. It is the antithesis of medical research... Self-reported, no control for any known bias effects, no scrubbing for obviously erroneous data.

Here's a VAERS entry about a patient turning getting abducted by aliens and turning into the Incredible Hulk after the MMR vaccine. https://www.medalerts.org/vaersdb/findfield.php?IDNUMBER=221...

Reasoning from VAERS without controlled studies is, at best, like cutting the ends off a roast before you bake it because you heard your grandmother did it that way. At worst, it's like irradiating a spider and enticing it to bite you because you read once that somebody got spider powers that way.
