I hope anyone who has an adverse event related to a vaccine reports it to Health and Human Services (if you're in the US) or your respective gov't agency.

Patients can report adverse events. Even suspected adverse events can/should be reported. This is how rare side effects can be identified and evaluated. A single report of tinnitus is unlikely to be flagged, but 10,000 reports? Absolutely.
