BOSTON, MASSACHUSETTS — A microbiologist who previously served as team leader for the Human Genome Project at Massachusetts Institute of Technology has studied the contents of mRNA vaccines and found severe contamination in the vials.
Kevin McKernan states that the vaccines contained high concentrations of DNA from simian virus 40 (SV40) – a monkey virus that has been linked to mesothelioma, lymphoma, brain and bone cancers in humans.

In 1961, Dr. Bernice Eddy, a scientist with the National Institute of Health’s Division of Biologics, discovered SV40 when she took the material used to manufacture polio vaccines and injected it into hamsters. The animals started growing tumors. This monkey virus contaminated both the Inactivated Polio Vaccine (IPV) and the Oral or "Live" Polio Vaccine (OPV). Despite this toxicity, these vaccines were given to children up through the 1990s.
"If McKernan’s findings are verified, the implications are serious. Widespread DNA contamination would bring into question the quality of the entire #mRNA injection manufacturing process, safety systems, and regulatory oversight."@JulesSladden https://t.co/8e8wbCIiu3

The highest concentration of DNA contamination that McKernan found amounted to 30 percent of the injection solution. That’s about 1,000 times higher than the European Medicines Agency’s safety limit.
“It's in both Moderna and Pfizer. We looked at the bivalent vaccines for both Moderna and Pfizer and only the monovalent vaccines for Pfizer because we didn't have access to monovalent vaccines for Moderna. In all three cases, the vaccines contain double-stranded DNA contamination,” McKernan said.
“At least on the Pfizer side of things, it has what's known as an SV40 promoter. This is an oncogenic virus piece. It's not the entire virus. However, the small piece is known to drive very aggressive gene expression. And the concern that people, even at the FDA, have noted in the past whenever injecting double-stranded DNA is that these things can then integrate into the genome,” McKernan stated on David Horowitz’s podcast Conservative Review.
Immunologist Dr. Sucharit Bhakti says that the DNA contamination in the vaccines is present in the liquid nanoparticle that delivers the mRNA spike protein into the body. This foreign DNA has the potential to enter cells and change the human genome in a vaccine recipient, which could transfer to chromosomes and carry over to children.

“If you inject a foreign gene, you are going to incite self-destruction in your body,” Bhakti said, calling for an immediate stop to the vaccine program as well as accountability for those involved.
Scientific teams in other countries, including France and Japan have confirmed McKernan’s findings.
A peer-reviewed Swedish study published last year revealed that the Pfizer mRNA shot can be integrated into the genome of human cells:
“Our study shows that BNT162b2 can be reverse transcribed to DNA in liver cell line Huh7, and this may give rise to the concern if BNT162b2-derived DNA may be integrated into the host genome and affect the integrity of genomic DNA, which may potentially mediate genotoxic side effects,” the team of scientists from Lund University stated in the journal Current Issues in Molecular Biology.
