Take a look at the viral claims, and find out what the facts really are!
Claim : mRNA Vaccines Are Contaminated With SV40 DNA!
Some people are sharing video clips, messages, and articles which claim that the mRNA COVID-19 vaccines from Pfizer and Moderna are contaminated with SV40 virus DNA that can cause turbo cancer and other health problems!

Yet another lab confirms therapeutic levels of DNA and SV40 contamination of Pfizer and Moderna “vaccines”
This time, @DJSpeicher & @JesslovesMJK show that the DNA contamination correlates to adverse events (and presumably deaths).
Criminal prosecutions are needed
💙Lyndsey, RN🐭 : Do NOT take Pfizer or Moderna as plasmid dna contamination and SV40 found in the vials that were distributed to the population. BUT the dna and sv40 were not found in the trial vials. HUGE REGULATORY ISSUE THERE FOR YOUR BIG MOMMA AND POP POP!
Chuck Callesto : BREAKING REPORT: Pfizer accused of NOT DISCLOSING the presence of the Simian Virus 40 [SV40] DNA sequence in its mRNA COV-D-19 vaccine.
The complete SV40 virus was ELIMINATED from Polio vaccines during the 1950s and 1960s because of concerns about its association with CANCER.

Truth : mRNA Vaccines Are Not Contaminated With SV40 DNA!
This is yet another example of FAKE NEWS created / propagated by anti-vaccine proponents, and here are the reasons why…
Fact #1 : SV40 Promoter Is Not SV40 Virus
First, I should point out that gene promoters are DNA sequences that stimulate gene expression, and have long been used in molecular biology.
The SV40 promoter is a DNA sequence that was derived from the SV40 (Simian Virus 40) virus, and is not the same thing as the SV40 virus DNA. Think of it as a genetic tool obtained from the SV40 virus, just like how botulinum toxin is a treatment derived from the bacteria, Clostridium botulinum.
Finding botulinum toxin in a vial of Botox does not mean there is bacteria in that vial. Similarly, finding the SV40 promoter in the Pfizer vaccine does not mean there is SV40 virus in the vaccine.
According to Professor David Gorski, a professor of surgery and oncology at the Wayne State University School of Medicine, “the SV40 promoter-enhancer is often used in plasmids because it is a very strong promoter that can drive the production of lots of the desired mRNA encoded by the cDNA sequence attached to it.”
Fact #2 : SV40 Promoter Is Not Dangerous
Michael Imperiale, a molecular biologist at the University of Michigan Medical School, explained that the SV40 promoter, on its own, can’t cause cancer. The part of SV40 that’s potentially cancer-causing, known as the T-antigen, isn’t present in the vaccine.
Even the scientist whose testimony to the South Carolina Senate has been used to drive this controversy, has come out to dismiss the concerns that the SV40 promoter is dangerous, or can cause cancer:
It’s just the volume knob that drives high level expression of anything put under its control, which in this case is just an antibiotic resistance marker.
The fear about the SV40 sequences is total nonsense. The vaccine is not going to cause cancer. There is no cancer causing gene in the vaccine.
– Phillip Buckhaults, director of the Cancer Genetics Lab at the University of South Carolina
Fact #3 : mRNA Vaccines Are Not Contaminated With SV40 Virus
To be clear – mRNA vaccines do not contain the SV40 virus, because they were manufactured using in vitro transcription (IVT) technology.
The presence of the SV40 virus in some of the polio vaccine manufactured from 1955-1963 occurred because that vaccine was manufactured in monkey kidney cell cultures that were contaminated with the SV40 virus.
Even then, decades later, there is still no conclusive evidence that the SV40 virus can cause cancers in humans. However, out of an abundance of caution, the SV40 virus is considered to potentially cause cancer in humans.
There is no evidence to indicate the presence of SV40, a virus found in monkey kidneys that can potentially cause cancer in humans, in the formulation of COVID-19 vaccines.
– Alessandro Faia, spokesperson for the European Medicines Agency (EMA)

Fact #4 : Health Canada + EMA Confirm Residual DNA Meet Regulations
Health Canada actually wrote a detailed explanation (archive) of why DNA fragments are expected in mRNA vaccine manufacturing, and why the quantity in the vaccines is not a concern.
Plasmids are an essential starting material for the production of mRNA vaccines. During the downstream process in mRNA vaccine manufacturing, the plasmid DNA is digested with enzymes to small fragments, and further removed to a level of not more than 10 ng/human dose, which is in line with the World Health Organization’s recommendation concerning residual DNA in biological drugs. The DNA is digested with enzymes post-transcription.
Health Canada was aware of the presence of residual plasmid DNA as a process-related impurity during review and prior to the authorization of the mRNA COVID-19 vaccines. In addition, the release testing data for every COVID-19 vaccine lot released into the Canadian market were reviewed and deemed to meet the requirements approved by Health Canada. Furthermore, different assays assessing the same vaccine property, or even the same assay being performed in different laboratories, may generate different results.
It is important to assess the results using the authorized validated assays performed by the vaccine manufacturers to ensure that the quality of commercial vaccine lots are comparable to lots shown to be safe and efficacious in clinical studies.
The European Medicines Agency (EMA) also concurred, stating that the SV40 sequence is considered “a non-functional part” of the DNA plasmid that was used to manufacture the mRNA vaccines:
We can confirm that an SV40 sequence is present in the DNA plasmid. The sequence is not directly relevant for plasmid production in E. coli or for the mRNA production process so it is considered to be a non-functional part of the structure of the source plasmid.
Specific sequences for the non-infectious parts of SV40 are commonly present in plasmids used for manufacturing of biological active substances. The sequence for non-infectious parts of SV40 is only a small fraction of the entire SV40 sequence.
While the full DNA sequence of the plasmid starting material was provided in the initial marketing authorisation application for Comirnaty, the applicant did not specifically highlight the SV40 sequence, as it was considered to be a non-functional part of the plasmid. They have since clarified this information in response to questions raised by EMA.
We would also like to point out that during the manufacturing process, this sequence and other plasmid DNA sequences are broken down and removed. Fragments of the SV40 sequence may only be present as residual impurities at very low levels that are routinely controlled.
In short – the mRNA vaccines meet regulatory limits for residual DNA. This isn’t new or shocking to Health Canada, or the EMA, or other regulatory agencies.

Fact #5 : mRNA Vaccines Meet Residual DNA Limits
The production of mRNA vaccines at scale do not use any animal cells, but is done through in vitro transcription (IVT). The enzyme DNase is then used to destroy the DNA template and polymerase used in the reaction, and further filtration can be performed to reduce the amount of DNA fragments.
In Canada, the limit was set at 10 ng of DNA per dose, which is in line with WHO recommendations. According to Health Canada, the mRNA vaccines all comply with this requirement.
The David J Speicher et al. preprint (which has not yet peer-reviewed) actually showed that the amount of residual DNA “contamination” was far below FDA regulatory limits.
As Professor David Gorski noted, the study authors found that the residual DNA in the mRNA vaccines was far below regulatory limits, and used a logarithmic scale to make them appear much closer to the limit than they really are:
Basically, by the authors’ own measurements, the amount of DNA/vial fell below the FDA guidance of 10 ng DNA/dose.
Did you also notice the little trick they did? They used a log scale to make the total DNA appear to be much closer to the FDA-recommended limit than it really is.
For instance, in all the Moderna vials, the amount of DNA isn’t half of the recommended limit, it’s less than one-tenth the recommended limit, and, in the case of the ori sequence, well under 1/100 of the limit.
The abstract itself even notes that the authors found DNA at “0.28 – 4.27 ng/dose and 0.22 – 2.43 ng/dose (Pfizer), and 0.01 -0.34 ng/dose and 0.25 – 0.78 ng/dose (Moderna), for ori and spike respectively measured by qPCR.”
So, from McKernan and Rose’s own data, the vial with the very highest concentration of DNA was one Pfizer vial that had less than one-half the maximum DNA amount recommended by the FDA, while the Moderna vial with the most plasmid DNA contamination had less than one-tenth the maximum recommended by the FDA.
In short – even the much touted Speicher preprint itself showed that the amount of residual DNA in mRNA COVID-19 vaccines are far below regulatory limits.
The whole controversy is really much ado about nothing. What a bloody waste of time!
Fact #6 : Residual DNA Won’t Integrate Into Our Genome
The presence of residual DNA itself does not mean that they will integrate into our genome. For one thing – these are DNA fragments that have been broken down by the DNase enzyme.
Think of them as parts of a factory which were used to build the mRNA vaccine, but dismantled once the vaccine has been manufactured. Sure, the disposal team may have left a couple of bolts and screws lying on the floor, but can they be used to recreate the factory? No.
To be clear – neither the COVID-19 vaccines, not any residual DNA they may contain, can change our genome. On top of that, the vaccines are injected into the muscle, whose cells are “post-mitotic”, which means they are no longer able to change.
