# VAERS: COVID19 × Myocarditis

VAERS reports are voluntary. Counts are reporting, not incidence. Disproportionate reporting is a hypothesis, not evidence of causation.

n is the sum of quarterly observed counts. Those counts are rolling windows, so n is not a count of unique reports.
n_unique is not in this extract. The signals parquet has no VAERS report id, so this service does not invent a distinct-report count.
eb05 is the peak quarterly EB05, the same number as Peak EB05 in the app. It is the raw quarterly EB05, not the EWMA.
eb05_peak_pre2021 is the highest quarterly EB05 before 2021Q1 on the series, with the earliest quarter that attains it. It is not a new statistic.
peak_in_covid_era is true when the vaccine is not COVID19 and the series peak quarter falls in 2021Q1-2022Q4.
background=no_covid is not served. Dropping COVID-19 vaccine reports and refitting GPS is a pipeline recompute, not a lookup.
sort=trend is not supported. This service does not derive a trend.
prr, ror, and ic are on format=series quarters. There is no ebgm column. eb50 on a quarter is the median, not an EBGM.

## Pairs

- COVID19 (COVID19 (PFIZER-BIONTECH)) × Myocarditis — peak EB05 3.07 (2026Q1) — pre-2021 peak none — peak_in_covid_era false — n 54540 — 21 quarters — 2021Q2 to 2026Q2 — COVID19
  COVID-19 vaccine reports are a large share of the VAERS background in 2021-2022, so this vaccine's own volume dominates the comparator.
- COVID19 (COVID19 (UNKNOWN)) × Myocarditis — peak EB05 2.22 (2023Q1) — pre-2021 peak none — peak_in_covid_era false — n 171 — 9 quarters — 2022Q4 to 2025Q1 — COVID19
  COVID-19 vaccine reports are a large share of the VAERS background in 2021-2022, so this vaccine's own volume dominates the comparator.
- COVID19 (COVID19 (MODERNA)) × Myocarditis — peak EB05 1.77 (2026Q1) — pre-2021 peak none — peak_in_covid_era false — n 233 — 5 quarters — 2025Q2 to 2026Q2 — COVID19
  COVID-19 vaccine reports are a large share of the VAERS background in 2021-2022, so this vaccine's own volume dominates the comparator.
- COVID19 (COVID19 (JANSSEN)) × Myocarditis — peak EB05 1.59 (2024Q4) — pre-2021 peak none — peak_in_covid_era false — n 34 — 4 quarters — 2024Q4 to 2025Q3 — COVID19
  COVID-19 vaccine reports are a large share of the VAERS background in 2021-2022, so this vaccine's own volume dominates the comparator.
- COVID19 (COVID19 (PFIZER-BIONTECH BIVALENT)) × Myocarditis — peak EB05 1.48 (2025Q1) — pre-2021 peak none — peak_in_covid_era false — n 40 — 3 quarters — 2024Q4 to 2025Q2 — COVID19
  COVID-19 vaccine reports are a large share of the VAERS background in 2021-2022, so this vaccine's own volume dominates the comparator.
