VaxDataCheck — Claim Verification Log

Every viral vaccine claim, checked against the record.

We take specific claims circulating online, trace them back to primary sources — VAERS, clinical trial data, CDC and FDA records — and publish the verdict with the sourcing attached. No spin in either direction.

Featured claim check

“There are over 30,000 reports of this reaction in VAERS — that proves the vaccine causes it.”

Unsupported

A report count alone doesn’t establish causation. VAERS is a passive, open reporting system — anyone can file a report, and reports aren’t verified before they’re logged. Report volume can rise for reasons unrelated to the vaccine itself, including increased public attention.

Our process

How we check a claim

01

Capture the claim

We quote or screenshot the claim exactly as it circulated, with a source and date.

02

Rank the sources

Primary data outranks secondary reporting, which outranks commentary.

03

State the caveats

Every use of VAERS or similar data includes the limitations, every time.

04

Publish the verdict

One of four ratings, with the full sourcing attached and a visible review date.

Stay checked

One email when a new claim gets checked.

No daily noise. Just the claim, the verdict, and the sourcing — sent when we publish, not on a schedule.
