Researchers Alarmed to Find DNA Contamination in Pfizer Vaccine

Phillip Buckhaults, a cancer genomics expert and professor at the University of South Carolina, has testified before a South Carolina Senate Medical Affairs Ad-Hoc Committee saying that Pfizer's mRNA vaccine is contaminated with billions of tiny DNA fragments.

In order to upscale the process for large-scale distribution of the vaccine to the population for its "Emergency authorisation" supply, Pfizer switched to a different method-PROCESS 2-to amplify the mRNA. PROCESS 2 used bacteria to make large quantities of "DNA plasmid", which would be used to make the mRNA. Hence, the final product contained both plasmid DNA and mRNA. The switch from PROCESS 1 to PROCESS 2, ultimately resulted in the contamination of the vaccine.

Genomics expert Kevin McKernan has also reported plasmid DNA contamination in both Pfizer and Moderna bivalent COVID-19 vaccines, in amounts that far exceeded the safety limit set by the FDA. FDA Safety Limits The FDA acknowledges that there are risks to having residual DNA left in vaccines: Residual DNA might be a risk to your final product because of oncogenic and/or infectivity potential.

There are several potential mechanisms by which residual DNA could be oncogenic, including the integration and expression of encoded oncogenes or insertional mutagenesis following DNA integration.

Chemical inactivation can decrease both the size and biological activity of DNA. The problem with this advice said Buckhaults, is that it applies to the manufacturing of traditional vaccines, which contain what is known as "Naked DNA." Normally, low levels of naked DNA in a vaccine would not be a problem because the bits of DNA are chewed up by tissue enzymes before they've had a chance to get inside cells.

The DNA in Pfizer's vaccine is not "Naked." It is wrapped up in lipid nanoparticles-essentially fat globules-that help transport the genetic material inside the cells where the DNA can migrate to the nucleus and insert itself into the genome.

That's why Buckhaults told the Senate that the FDA's rules for safe levels of DNA in vaccines do not apply to the new mRNA platform technology.
