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.
Why this page exists
Searches for long covid treatment, ldn for long covid, and naltrexone long covid reflect a treatment-research audience distinct from vaccine safety database queries — but overlapping in post-COVID syndrome interest.
OSMF / VitalScan connection
The Open Source Medicine Foundation runs patient-centred research including the PACVS (post-acute COVID vaccine syndrome) navigator and VitalScan protocol work. Vaccine pharmacovigilance data on this site informs safety context; treatment trials live at opensourcemed.info.
Vaccine safety data cross-link
For COVID vaccine adverse-event database reports (distinct from long COVID treatment), see COVID vaccine side effects — VAERS at scale.
