COVID lot adverse-event data explorer

Passive VAERS reporting data (2006–2024) × openVAERS per-lot doses. Category values are the % of a lot’s reports mentioning that symptom group. Rates are reporting rates per million doses — not incidence, not causal. Hypothesis-generating only.

Lot × serious-PT signals surviving overdispersion correction (FDR<0.05)

Within-manufacturer, dose-denominated. 47 of 3,094 tested cells (naive Poisson flagged 742; dispersion φ=16). Survivors are dominated by Death in early large lots — confounded by elderly-first rollout, not batch toxicity.
