Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

•State of reporter: Reports are attributed to where the reporter lives, which may differ from where vaccination occurred.
•Reporting culture varies: States with more awareness of VAERS or mandated reporting may have higher per-capita rates.
