What the Evidence Shows

The claim originates from statements by attorney Aaron Siri during a U.S. Senate hearing, referencing a large Henry Ford Health System birth cohort study reportedly tracking 18,468 children over 10 years. The study allegedly found vaccinated children had higher rates of chronic illness and neurodevelopmental disorders compared to unvaccinated children.childrenshealthdefense.orgchildrenshealthdefense.orgAuthors of ‘Astonishing’ Study Showing Unvaccinated Kids Are Healthier Refused...thefocalpoints.comthefocalpoints.comBREAKING: Henry Ford Birth Cohort: Vaxxed vs. Unvaxxed, Reported Vaccinated Kids...+1 more

This study has not been published in any peer-reviewed journal, nor has it undergone scientific scrutiny. The authors reportedly refused to go public with the results, and the data or methodology have not been independently verified.debatepolitics.comdebatepolitics.comAuthors of ‘Astonishing’ Study Showing Unvaccinated Kids Are Healthier Refused...publichealthpolicyjournal.compublichealthpolicyjournal.comAuthors of ‘Astonishing’ Study Showing Unvaccinated Kids Are Healthier Refused...+1 more

Larger, reputable epidemiological studies consistently find no greater incidence of adverse health outcomes in vaccinated children compared to unvaccinated children.

The narrative that the study was 'buried' or deliberately hidden is based on anecdotal claims without corroborating evidence. There is no official confirmation from Henry Ford Health System or independent scientific bodies that such suppression occurred.x.comx.comDavid Sunfellow on X: "GROK, what study is Del Bigtree referring to here?

Social media posts by individuals like Dr. Peter McCullough amplify these claims but do not provide access to the underlying data or peer-reviewed publication.x.comx.comPeter A. McCullough, MD, MPH® on X: "BREAKING: Henry Ford Birth Cohort Study:...

In summary, while Aaron Siri has publicly discussed an unpublished Henry Ford study suggesting unvaccinated children are healthier, the claim that this study was 'buried' is unsubstantiated. The study itself lacks peer review and has been criticized for serious methodological issues. Therefore, the assertion is misleading without stronger evidence.
