Enter a lot number to see its VAERS reports; volume-adjusted z-score flags, seriousness breakdown, and per-lot signal tables across all vaccines.
Open the dashboard →Enter a COVID lot number and a specific adverse event to see how many VAERS reports name that event for that lot, with the per-dose rate and a COVID-wide comparison.
Open the lookup →The raw data behind these analyses: 605 COVID lots with reports, doses, dose-denominated rates, symptom-category profiles, and cluster labels — sortable and filterable.
Browse the data →Reports, serious reports, and deaths per million doses for each lot, using openVAERS dose denominators. A count-vs-rate scatter shows how lots rank by raw report count versus by rate per dose.
View per-lot rates →Reporting rate per million doses for each adverse event, computed with known lot doses (840M) and with all lots including imputed doses (924M). The rates are stable across both.
View AE rates →Searchable, sortable table of reporting rates for all 11,000+ individual MedDRA adverse-event terms, with summary bars for total, serious, hospitalization, and death rates.
Open the full table →Box-and-whisker plots of how each adverse event’s rate varies from lot to lot — totals, categories, and individual terms — shown crude and age-adjusted.
View distributions →A cluster analysis (Hopkins, silhouette, k-means, density scan) of the reported symptom mix. It did not identify distinct batch-specific clusters; the largest identifiable sources of variation were manufacturer platform and reporting era.
Read the analysis →When the lots flagged for elevated reporting were administered, and to whom — compared against the documented ACIP rollout phases (healthcare workers, then elderly / long-term care) using vaccination date and recipient age.
