(LifeSiteNews) — A new preprint study claims to have discovered “significant levels” of “plasmid DNA” in expired COVID-19 vaccines, impurities the researchers say may be linked to adverse events. The study, which is not yet peer-reviewed, calls for “further investigation” to corroborate the findings.
On Thursday, The Center for Open Science’s OSF Preprints posted a preprint study claiming to have discovered “plasmid DNA at significant levels in both Pfizer-BioNTech and Moderna modRNA vaccines.”
In the 31-page study, authors David J. Speicher, Jessica Rose, L. Maria Gutschi, David M. Wiseman, Ph.D., and Kevin McKernan said they had found “billions to hundreds of billions of DNA molecules per dose” that they gathered from “Expired unopened vials of Pfizer-BioNTech [shots] … and Moderna Spikevax mRNA” jabs “obtained from various pharmacies in Ontario, Canada.”
McKernan has argued that the alleged contamination could trigger serious health problems, including cancer.
“Our findings extend existing concerns about vaccine safety,” the authors said in the preprint, adding that the results also “call into question the relevance of guidelines conceived before the introduction of efficient transfection using [lipid nanoparticles].”
Pfizer and Moderna’s COVID-19 jabs contain lipid nanoparticles (LNPs), which are “tiny balls of fat” that act as delivery mechanisms for the mRNA vaccine.
The authors of the preprint noted that their research had been conducted “[w]ith several obvious limitations,” and urged a replication of their procedures “under forensic conditions.” They also called for guidelines to be “revised to account for highly efficient DNA transfection and cumulative dosing.”
According to the researchers, the “preliminary evidence of a dose-response effect of residual DNA measured with qPCR [quantitative polymerase chain reaction] and SAEs [severe adverse events] warrant confirmation and further investigation.”
The preprint’s authors have raised concern about vaccine contamination in the past.
In June, a preprint published by McKernan his fellow researchers and reported on by Joseph Mercola alleged that a fragment of a “monkey virus” genome, SV40, had been discovered in the COVID-19 jabs.
The report pointed out that SV40, previously discovered in polio vaccines in the 1950s and 1960s, was linked to cancer. However, Health Feedback has noted that the DNA found in the COVID jabs was only a “fragment” of the genome, and that it’s unclear whether SV40 causes cancer in humans (current research only supports risk of cancer in certain animals).
Moreover, the polio jabs became contaminated due to the use of monkey kidney cells to grow the virus, Health Feedback noted, cell cultures that were not used in the making of the Pfizer shots — throwing doubt on how the SV40 contaminants got into the injections to begin with. Instead of monkey cells, the Pfizer and Moderna shots were developed using aborted human fetal cell lines, sparking major concerns for pro-life advocates and ethicists.

The concerns raised in the new preprint add to existing worries about the many remaining unknowns and potential risks connected to mRNA COVID-19 jabs.
Dr. Robert Malone, a pioneer of mRNA vaccine technology, has said that “gene therapy” is an accurate term for COVID jabs, and that he didn’t recommend that anyone, even the elderly, get vaccinated due to the potential for adverse effects.
Moreover, as LifeSiteNews has extensively reported, Americans have long expressed serious skepticism about COVID-19 shots due to their failure to provide lasting protection, inability to stop transmission, and links to serious side effects, up to and including death.
Skeptics of the push to get the jabs and their follow-up booster also remain concerned that the vaccines have not been sufficiently studied for negative effects given their accelerated clinical trials, and some harbor ethical reservations about the use of cells from aborted babies in their development. Still others simply consider them unnecessary given COVID-19’s high survivability among most groups, low risk of asymptomatic spread, and research indicating that post-infection natural immunity is equally protective against reinfection.
Concerns about the risks of the jabs and their lack of beneficial effects has led to decreased demand for updated booster shots.
As of this month, only about 7 million Americans — roughly two percent (2%)— have gotten the newest COVID booster shots produced by Moderna, Pfizer, and BioNTech.
