COVID Lot Reactogenicity AE Rates

Reports per Million Doses by Manufacturer

Comparing 9 common reactogenicity adverse events across lots with known (openVAERS) vs. model-estimated dose denominators. Data: VAERS COVID-19 lots, 2020–2024.

⚠️ Critical Caveats

How to read this chart: Each pair of bars shows the mean reporting rate (per million doses) for one adverse event. Blue = known doses (actual openVAERS denominators, n=541 lots across 3 manufacturers). Orange = estimated doses (model-derived denominators, n=499 lots with ≥20 index events, not in the known set). Values printed on bars are reports per million.
