Pharmacovigilance — Vaccine Safety Surveillance Glossary & Data Sources

How to read database counts: Pharmacovigilance systems (VAERS, EudraVigilance, Yellow Card, VigiBase, Lareb, DAEN) collect spontaneous, unverified reports. A report is not a confirmed adverse event and does not prove the vaccine caused the outcome. Under-reporting, stimulated reporting, and missing denominators limit rate interpretation. Compare with trials and epidemiological studies on each page before drawing conclusions.

Definition

Pharmacovigilance is the science of detecting, assessing, and preventing adverse effects of medicines and vaccines. For vaccines, national systems (VAERS, EudraVigilance, Yellow Card, VigiBase, Lareb, DAEN, JADER) collect spontaneous reports; active systems like VSD analyse linked health records.

CDC and Mayo answer "what are the side effects" with clinical guidance. This site answers the same query with what reporters filed — counts, categories, and lot tools — plus explicit causation limits.
