All (vaccine, event) pairs flagged by ≥2 of 4 disproportionality methods (GPS/EBGM, PRR, ROR, IC) across VAERS data through 2026Q2 . The splash shows the top 2000 by Peak EB05 ; use search to find any other pair. Click any row to see the time-course plot.
Vaccine Type groups vaccines by type (COVID19, INFLUENZA, MMR, etc.). Emerging (amber) marks pairs that first appeared in the last 4 quarters of the dataset.
VAERS caveat: VAERS reports are submitted voluntarily; counts reflect reporting rates, not incidence rates. Disproportionate reporting is a statistical hypothesis generator, not evidence of causation. Vaccine-event pairs with large counts may reflect reporting campaigns rather than safety signals.
Bayesian and frequentist disproportionality analysis over CDC VAERS data through 2026Q2 . Signals are precomputed offline via the same R/targets pipeline used for faers.mobi and served as read-only parquet for interactive exploration.
VAERS is a national vaccine safety surveillance system jointly managed by the FDA and CDC. Reports are submitted voluntarily by healthcare providers, manufacturers, and the public. VAERS data are released annually at vaers.hhs.gov .
Per-year rolling 4-quarter window with cumulative-fit prior. All (vaccine, event) pairs flagged by ≥2 of 4 methods are included.
VAERS reports are submitted voluntarily. Counts reflect reporting rates, not incidence rates. A disproportionate reporting ratio does not prove causation. Large counts may reflect reporting campaigns, media coverage, or recall bias rather than a true vaccine-event association. Treat signals as hypotheses for further investigation.
