Health Canada on Thursday confirmed the presence of DNA contamination in Pfizer COVID-19 vaccines and also confirmed that Pfizer did not disclose the contamination to the public health authority.
In what one scientist described as an “admission of epic proportions,” Health Canada on Thursday confirmed the presence of DNA contamination in Pfizer COVID-19 vaccines, and also confirmed that Pfizer did not disclose the contamination to the public health authority.
The DNA contamination includes the Simian Virus 40 (SV40) promoter and enhancer Pfizer did not previously disclose and that some experts say is a cancer risk due to potential integration with the human genome.
Health Canada, the country’s public health authority, told The Epoch Times that while Pfizer provided the full DNA sequences of the plasmid in its vaccine at the time of the initial submission, the vaccine maker “did not specifically identify the SV40 sequence.”
“Health Canada expects sponsors to identify any biologically functional DNA sequences within a plasmid (such as an SV40 enhancer) at the time of submission,” it said.
Health Canada’s admission came after two scientists, Kevin McKernan and Phillip J. Buckhaults, Ph.D., discovered the presence of bacterial plasmid DNA in the mRNA COVID-19 vaccines at levels potentially 18-70 times higher than the limits set by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency.
They tested four expired Pfizer and Moderna vaccine vials “thought to only contain mRNA” and found to contain “double-stranded DNA plasmids.”
Health Canada said, “We have concluded that the risk/benefit profile continues to support the use of the Pfizer-BioNTech vaccine,” and that it does rely on manufacturer claims but “conducts an in-depth independent review” to make sure the vaccines meet “our high standards for safety, efficacy and quality.”
Janci Lindsay, Ph.D., director of toxicology and molecular biology for Toxicology Support Services, told The Defender this statement is “silly, not believable and not defendable,” adding that “We should not have to do the research that they should have done.”
“Why are the FDA, CDC [Centers for Disease Control and Prevention] and the mainstream media still silent about this?” asked Steve Kirsch, founder of the Vaccine Safety Research Foundation, adding that “the mainstream medical community is silent as well.”
Bridle also wrote:
“One must wonder why Pfizer would not disclose the presence of a biologically functional DNA sequence to a health regulator. Pfizer was required to disclose to health regulatory agencies all of the bioactive sequences in the bacterial plasmid DNA that they used to manufacture their shots.”
The contamination “would have been discovered sooner by independent researchers, but people were threatened with arrest if they supplied vials for analysis,” Kirsch said, claiming he faced threats if he “participated in trying to analyze the vials.”
Bridle noted that it’s been “818 total days” since the University of Guelph banned him from accessing his office and laboratory for attempting to conduct similar research, while other researchers “have been the focus of attacks from many so-called ‘misinformation experts,’” even though none “have been able to refute their findings.”
