In a
U.S. Senate hearing today, attorney Aaron Siri revealed the results [
Siri-Teastimomy] of a large study that found vaccinated children were far more likely to develop chronic disease than unvaccinated kids.
The study never underwent peer review and was never published, because the authors — staunch vaccine supporters — told Siri they were concerned about losing their jobs or reputations because their findings contradicted the official public health narrative and vaccine policy.
Siri’s testimony, delivered during Tuesday’s Senate hearing, “How the Corruption of Science has Impacted Public Perception and Policies Regarding Vaccines,” addressed the study’s origins, findings and suppression.
The study involved over 18,000 children enrolled in Henry Ford Health system’s insurance plan in Michigan.
“The results are astonishing,” Siri told The Defender. “For example, vaccinated children had 4.29 times the rate of asthma, 3.03 times the rate of atopic disease (a group of allergic conditions), 5.96 times the rate of autoimmune disease, and 5.53 times the rate of neurodevelopmental disorder.”
These findings were statistically significant — even when accounting for gender, race, birthweight, premature birth, and respiratory distress or trauma at birth.
But rather than publishing the results, the study authors and their bosses at Henry Ford Health refused to make them public — even though the lead author previously assured Siri and Del Bigtree he would publish the results, whatever the findings...
The study authors divided kids into two groups: vaccinated and unvaccinated. Nearly 2,000 were in the unvaccinated group. Roughly 16,500 kids received one or more vaccines, with the median number of vaccines being 18.
The authors found links “between vaccination and the incidence of asthma, atopic and autoimmune disease, and mental health and neurodevelopmental disorders including developmental delay and speech disorder,” according to a copy of the study Siri obtained.
The authors calculated incident rate ratios — the odds that a vaccinated child would develop a given medical condition versus an unvaccinated child. Overall, vaccinated children were 2.48 times more likely to be diagnosed with a chronic health condition than unvaccinated kids.
Vaccinated children were over four times more likely to be diagnosed with a speech disorder than unvaccinated children, and nearly six times more likely to be diagnosed with an autoimmune disease...
According to Siri, the Henry Ford Health study came about after the Informed Consent Action Network (ICAN) in early 2017 searched for a highly qualified scientist to do a study comparing health outcomes between vaccinated and unvaccinated kids...
Siri and Bigtree initially thought it would be advantageous for the study to analyze children’s health data from the Centers for Disease Control and Prevention’s Vaccine Safety Datalink (VSD) database. But accessing VSD data was a complicated proposition.
Zervos instead suggested he and his colleagues do the study using data they already could access through Henry Ford Health’s vast database. Henry Ford Health runs over 550 medical sites in Michigan...
In early 2020, Siri received a copy of the study but discovered that it had not been submitted to a journal for publication.
Lois Lamerato, Ph.D., who had worked on the study with Zervos, told Siri she and Zervos both thought the study was well done and worthy of publication.
But the “higher-ups” at Henry Ford Health, to whom she was required to send a copy before submission, did not want to submit it. Lamerato also said she was worried the study, if published, would make doctors feel uncomfortable.
According to Siri, Henry Ford Health officials didn’t provide any substantive explanation for not wanting the study published.
