Pharmacovigilance Lot Signal Detection — Hypothesis-Generating Only

⚠️ Critical Caveats — Read Before Interpreting

Lot numbers in VAERS are incomplete and voluntary.
No lot-specific denominators are publicly available. Larger lots generate more reports.
A signal flag does NOT mean a lot is unsafe. It means a statistical threshold was exceeded.
These data are hypothesis-generating only. VAERS cannot establish causality.
Other pharmacovigilance systems (Canada Vigilance, EudraVigilance, etc.) are shown at product level — their public extracts do not include lot/batch fields.

New — dose-denominated COVID lot rates. The counts below are not divided by doses. Using third-party per-lot dose denominators from openVAERS (validated against their published rates at r = 0.999 for deaths), we computed reporting rates per million doses for 521 COVID lots — and show how the raw “hot lots” reshuffle once dose volume is accounted for.

Pharmacovigilance systems covered — only VAERS provides lot-level fields in the public data used here.

System	Region	Lot data	Notes
VAERS	United States	Lot data	Lot-level signal tables on this page (VAX_LOT field; ~69% coverage).
Canada Vigilance	Canada	No public lot field	Public CV Online extract has no lot/batch field — product-level counts only.
JADER (PMDA, Japan)	Japan	No public lot field	JADER public CSV (demo/drug/reac/hist) — MedDRA/J terms; no lot field in open data.
Lareb (Netherlands)	Netherlands	No public lot field	Vaccine schema index with per-vaccine databank links (ATC-coded); no public bulk extract or lot field.
EudraVigilance	European Union	No public lot field	Public line listings are not lot-stratified.
VigiAccess (WHO)	Global	No public lot field	Aggregate search only.
Yellow Card (UK)	United Kingdom	No public lot field	iDAP reaction summaries; no public lot breakdown.
DAEN (Australia)	Australia	No public lot field	Public search; lot not in open export.
