VAERS is an EVENT reporting system. It’s there so you can report any adverse event that takes place, regardless of whether the vaccine had anything to do with it because with all those reports, you can apply statistical models to find unexpected patterns that may indicate an actual problem worth investigating. It’s there to find that one-in-a-million set of circumstances that leads to a bad reaction that nobody would otherwise be aware of. VAERS reports were NEVER intended to be taken as gospel. The people who operate VAERS tell you that directly, all over the VAERS website: https://vaers.hhs.gov/data/dataguide.html
