Former Pfizer Toxicologist’s Book Alleges COVID-19 Shots Were Sold Without Proper Safety Testing
Dr. Helmut Sterz, a former chief toxicologist at Pfizer, has written a book alleging that the Wuhan coronavirus (COVID-19) mRNA vaccines were sold without proper safety testing.
The book, scheduled for release Aug. 26, is titled “The Vaccine Mafia: Pfizer’s Former Chief Toxicologist Proves How Toxic Substances Were Unlawfully Sold to Us as a Solution for Covid-19,” according to an Aug. 10 article published by author John Leake’s on the Focal Points Substack page. A product description published by Children’s Health Defense says Sterz’s book examines “the many ways the vaccines’ inadequate or omitted preclinical safety testing put the world’s population at risk” [1].
Leake, who wrote the book’s foreword, described Sterz as one of the most important witnesses concerning the COVID-19 mRNA vaccine program. Leake also characterized the program as a “global organized criminal enterprise.”
Toxicologist’s Career Spanned Three Decades in Pharmaceutical Safety Testing
According to Leake, Sterz performed toxicology research for major pharmaceutical companies from 1974 to 2009. From 2001 to 2009, Sterz served as CEO of Global Research and Development at Pfizer’s laboratory in Amboise, France, where he was responsible for toxicology analysis of the company’s drug portfolio in Europe.
Leake reported that he interviewed Sterz in 2024 and that Sterz “confirmed my worst suspicions” about the vaccine program. Sterz’s professional background in pharmaceutical toxicology is also cited in the Children’s Health Defense product description [1].
Book Claims Vaccines Were Administered Without Proper Toxicology Analysis
Sterz’s book alleges that Pfizer-BioNTech mRNA vaccines were injected into hundreds of millions of people without proper toxicology analysis, according to Leake’s article. Leake wrote that those responsible “created the Pharma Lab equivalent of a Pandora’s Box” that released sickness and death.
Leake said his initial suspicion, formed in April 2020, was that the vaccine was “a fait accompli” and that “no proper trials and toxicology would be performed.” Separate regulatory disclosures have drawn attention to vaccine composition.
Health Canada confirmed in January 2024 that Pfizer COVID-19 vaccines contain DNA contamination, including the simian virus 40 promoter and enhancer, according to Michael Nevradakis [2]. A December 2024 article by NaturalNews.com reported that scientists renewed calls for a moratorium on mRNA COVID-19 vaccines, citing safety concerns and incomplete data [3].
Early Statements From Gates, Foundation Officials Preceded Vaccine Rollout
Leake’s article cited an April 6, 2020 appearance by Bill Gates on “The Daily Show,” during which Gates said “a vaccine is the only thing that will allow us to return to normal.” Gates also announced that his foundation would invest billions in building vaccine manufacturing factories before conclusive efficacy data were available, according to the article.
Peter and Ginger Breggin wrote that Gates announced he had been funding and implementing plans with Moderna to rush through vaccines for an anticipated pandemic [4]. Mark Suzman, CEO of the Gates Foundation, told CNN: “We then need to be ready to scale and manufacture that vaccine in literally hundreds of millions and billions of doses because it needs to go global when we have it,” according to Leake.
Book Release and Pre-Order Details
Leake called the book “a treasure trove of documented factual information and analysis” and expressed hope that it would reach the New York Times bestseller list. Pre-orders are available through the Children’s Health Defense store [1]. Other former industry officials have made related statements.
Mike Yeadon, a former vice president and chief scientific adviser for Pfizer, said in print: “I tried to follow the science, but it was simply not there. I then followed the money; that’s where I found the science” [5].
Dr. William Makis, in a Nov. 20, 2024 interview with the Health Ranger Mike Adams, said an autopsy study on sudden deaths in vaccinated individuals “faced multiple rejections from prestigious journals like The Lancet” and “took two years to finally be published due to intense censorship” [6].
