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.
“There are over 30,000 reports of this reaction in VAERS — that proves the vaccine causes it.”
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.
Primary sources back the claim as stated.
True in part, but missing context that changes the picture.
Primary sources contradict the claim, or don’t show what’s claimed.
No primary source exists yet to confirm or refute it.
Sample entries below illustrate the claim-check format ahead of full launch.
“30,000+ VAERS reports proves this vaccine causes the reaction.”
Partially Supported“This vaccine was pulled from the market in several countries over safety concerns.”
Partially Supported“Vaccines still contain mercury-based preservatives.”
Unable to Verify“A specific batch was linked to a cluster of reactions in one state.”
Supported“Reported side effects vary between vaccine platforms.”
Unsupported“Long-term safety data doesn’t exist for any recent vaccine.”
What the system tracks, who can file a report, and why a report existing doesn’t mean a vaccine caused it. The single most useful page for reading any vaccine claim critically.

Read this month’s numbers →We quote or screenshot the claim exactly as it circulated, with a source and date.
Primary data outranks secondary reporting, which outranks commentary.
Every use of VAERS or similar data includes the limitations, every time.
