Health Canada confirms that Pfizer COVID-19 injections contain SV40 DNA sequence that can cause CANCER
11/01/2023 // Laura Harris // Views

Canada's Department of Health (Health Canada) has confirmed that the cancer-causing Polyomavirus Simian Virus 40 (SV40) sequence is indeed present in Pfizer's Wuhan coronavirus (COVID-19) mRNA vaccines.

The agency said in an email to the Epoch Times that vaccine sponsors are expected to identify any biologically functional DNA sequences within a plasmid, including SV40 enhancers, when submitted for review.

However, Pfizer did not specifically identify the SV40 sequence at the time of submission. Dr. Janci Lindsay of Toxicology Support Services (TSS) accused the New York-based vaccine maker of hiding the SV40 sequence not just from Canadian authorities, but also from the U.S. Food and Drug Administration and the European Medicines Agency.

"It's not just the fact that they're there, it's the fact that they were purposefully hidden from the regulators," said Linsday, who serves as the director of toxicology and molecular biology for TSS. She explained that while Pfizer's COVID-19 injection does not contain the full SV40 virus, it contains a nuclear localization sequence. When integrated into the human genome through insertional mutagenesis, SV40 promoters can lead to gene mutations that could potentially cause cancer.

SV40 was first discovered in the kidney cells of rhesus monkeys and later used to make both the inactivated polio vaccine injected using a syringe and the oral polio vaccine. However, SV40 was found to cause cancer in animals – leading to the passage of a law in 1961 that prohibited its inclusion in vaccines.

Health Canada still approves Moderna vaccines despite discovery of SV40

Two researchers – microbiologist Kevin McKernan and cancer genomics professor Dr. Phillip Buckhaults – had already disclosed the presence of SV40 promoters in Pfizer's mRNA COVID-19 vaccine back in May.

Just like Lindsay, McKernan accused Pfizer of not disclosing the presence of SV40 in the COVID injections given its historical link to cancer when used in polio vaccines several decades ago. He warned the public that SV40 promoters pose a potential concern due to the risk of integrating into human genomes near oncogenes.

In June, Dr. Joseph Mercola also touched on the issue in an op-ed for LifeSiteNews. He discussed the conversation between McKernan and Drs. Steven Greer and Sucharit Bhakdi about the SV40 promoters mixed in with the COVID-19 vaccines. According to Mercola, McKernan and his team detected SV40 in both the Pfizer and Moderna vaccines.

According to Greer, the vaccines could alter the human genome and cause the permanent production of a harmful spike protein – prompting the immune system to attack healthy cells. He added that governments and drug companies might have misled the world to a greater extent than previously known.

For his part, Mercola surmised that the presence of SV40 in the vaccines might be due to quality control issues in the manufacturing process. Such errors, he noted, could also explain the high number of anaphylactic reactions associated with the vaccines.

Despite the mounting evidence regarding the adverse effects of COVID-19 vaccines, Health Canada still approved revised Moderna mRNA-based COVID-19 shots.
