What was claimed

An independent lab tested 5 common childhood vaccines and all came back positive for glyphosate (cancer-causing chemical from Roundup); the MMR vaccine had levels 25x higher than the others because it uses pig gelatin from GMO-fed pigs. They are injecting carcinogens into children

Our verdict

Needs caution

Glyphosate is the active ingredient associated with Roundup, but the cancer claim is disputed and not settled by the provided sources. The sources specifically note that evidence on cancer is contradictory. While glyphosate was detected, the detected levels (2.671 ppb in MMR) are below EPA's allowable daily intake levels for adults. The claim ignores dose-response relationships and regulatory safety assessments. Calling trace amounts 'carcinogens being injected' is inflammatory and lacks scientific nuance.

Detailed Analysis

The response mixes a real 2016 screening claim with unsupported and misleading conclusions. The underlying vaccine glyphosate results came from a non-peer-reviewed ELISA screening and were specifically criticized as unreliable for vaccines, while no cited source supports the leap that children are being injected with carcinogens.[1] [8] [9] The pig-gelatin/GMO-fed-pigs explanation is also not established by the provided sources.[1] [2]

Why this verdict

  • The response mixes a real 2016 screening claim with unsupported and misleading conclusions.
  • The underlying vaccine glyphosate results came from a non-peer-reviewed ELISA screening and were specifically criticized as unreliable for vaccines, while no cited source supports the leap that children are being injected with carcinogens.[1] [8] [9] The pig-gelatin/GMO-fed-pigs explanation is also not established by the provided sources.[1] [2]

Claims checked

They are injecting carcinogens into children.

Incorrect89%
The supplied sources do not support this conclusion, and one source says there is no reliable evidence that glyphosate is present in vaccines and that the testing method can produce false positives.[8] [9] The claim also overstates the evidence by treating an unconfirmed screening result as proof of carcinogenic exposure.

This claim may mislead readers without added context.

The provided sources do not establish this causal explanation. They mention gelatin-related discussion only indirectly, but do not verify that GMO-fed pig gelatin caused the reported result.[1] [2]

What other AI think

The statement contains a mix of claims with varying degrees of support. Some specific findings from the Moms Across America testing are accurate, but critical context is missing about testing methodology, regulatory disagreement on carcinogenicity, and the significance of detected levels. The claim about "injecting carcinogens" oversimplifies a complex scientific debate.

Glyphosate is a cancer-causing chemical

Misleading85%
The WHO's IARC classified glyphosate as 'probably carcinogenic' in 2015, but the EPA concluded in 2020 that glyphosate is 'not likely to be carcinogenic in humans.' Regulatory agencies disagree on carcinogenicity; calling it definitively 'cancer-causing' overstates the scientific consensus.

This claim may mislead readers without added context.

MMR uses pig gelatin from GMO-fed pigs

Verified80%
Sources confirm MMR is grown on gelatin made from bones and ligaments of commercially raised pigs and cattle fed GMO feed. This is a plausible source of glyphosate contamination.
The statement mixes a few verifiable facts (MMR contains hydrolyzed porcine gelatin) with claims based on small, non‑peer‑reviewed tests and speculative causal links. Independent NGO/press releases have reported ELISA detections of glyphosate in some vaccine samples, but methods, validation, and independent confirmation are lacking. Major public‑health agencies and credible fact‑checks find no reliable evidence that routine childhood vaccines contain harmful levels of glyphosate.

Claims checked

An independent lab tested 5 common childhood vaccines and all came back positive for glyphosate

Misleading70%
Advocacy groups published small ELISA-based tests claiming glyphosate detections in several vaccines, but the assays, lab validation, and peer review are inadequate and no independent, validated confirmations by regulatory labs exist.

This claim may mislead readers without added context.

Because it uses pig gelatin from GMO-fed pigs

Misleading75%
MMR formulations do contain hydrolyzed porcine gelatin, but there is no reliable evidence linking gelatin sourcing or 'GMO-fed' pigs to documented glyphosate contamination in final vaccine products.

This claim may mislead readers without added context.

They are injecting carcinogens into children

Misleading80%
There is no credible evidence that vaccines contain glyphosate at levels shown to cause cancer; glyphosate's carcinogenicity is debated (IARC vs other agencies), and public‑health authorities report no validated safety signal from vaccines on this issue.

This claim may mislead readers without added context.
