Replicating the findings of American scientists Kevin McKernan and Phillip Buckhaults, the German biologist Jürgen O. Kirchner has also found massive levels of DNA contamination in vials of the BioNTech-Pfizer mRNA vaccine deployed in the home country of the vaccine, Germany. Although commonly referred to as the ‘Pfizer’ vaccine outside of Germany, the vaccine was in fact developed by the German company BioNTech and BioNTech is its legal manufacturer.
Whereas Pfizer manufactures the mRNA for U.S. supply of the finished drug, BioNTech itself is responsible for manufacturing the mRNA for EU supply in partnership with European subcontractors. This does not appear to have made any difference for the issue of DNA contamination, however.
Kirchner first warned about the problem of DNA contamination of the BioNTech vaccine already in 2022 in the book Die mRNA-Maschine – ‘The mRNA Machine’ – which he published under the pseudonym David O. Fischer. The book contains an entire chapter on ‘The DNA Contamination of BioNTech’s mRNA Vaccine and its Risks’ and cites European Medical Agency documents which acknowledge the problem without quantifying it.
In the meanwhile, however, Kirchner himself procured five unopened vials of the BioNTech vaccine and submitted them for analysis to the Magdeburg-based lab of Professor Brigitte König of Leipzig University Hospital. The results of Prof.’s König’s analyses are summarised in the below table. Prof. König found massive DNA contamination, up to 354 times higher than the 10 nanogram per dose limit recommended by the WHO and applicable in the EU. Like Kevin McKernan, she also found full residual bacterial plasmids. The plasmids are used in the industrial production process of the mRNA (‘process 2’), which differs in this respect from the process which was used to produce vaccine batches for the clinical trials of the drug (‘process 1’).

The table is adapted from Kirchner’s August 9th letter to the German regulator, the Paul Ehrlich Institute (PEI), calling for “the immediate withdrawal of BioNTech’s Comirnaty mRNA vaccine from the market” on account of the DNA contamination. (The letter is attached to Kirchner’s September 16th letter to German Minister of Health Karl Lauterbach, which is available here.)
In the same August 9th letter, Kirchner also criticised the Paul Ehrlich Institute for failing to perform adequate quality control of the vaccine before approving batches for release. As noted in the letter, and also touched upon in my previous articles here, here and here, the PEI is responsible for batch release of the BioNTech-Pfizer vaccine not only for Germany but the entire EU.
Citing one of the PEI’s own publications, Kirchner notes in particular that it does not test the purity of the vaccine solution:
Instead, a “visual inspection” is conducted, whose usual standard, looking at the vaccine solution on a white and on a black background, only allows crude contaminants to be identified: like, for example, if a bug fell into the vaccine when the vial was being filled. DNA or protein contamination cannot be identified in this way. It appears that the required testing of the purity of the solution was systematically not done.
In an interview with the German edition of the Epoch Times, Kirchner notes that whereas the PEI did not conduct advanced testing for contaminants of the BioNTech vaccine – even though the EMA had already identified the risk of DNA contamination in the industrial production process – it did require such testing for the Novavax COVID-19 vaccine, which is based on more traditional recombinant protein technology:
A vaccine [Novavax] which can be very purely produced was tested for contamination and the mRNA vaccine, which cannot be purely produced at all for mass consumption, that one is not tested. So, one has to wonder: why is that?
As I have written about before, there is a longstanding, collaborative relationship between the German regulator – the Paul Ehrlich Institute – and the firm BioNTech. Questions are now being asked about how collaborative it is.

Here is a very good interview between Maryanne Demasi and Dr Phillip Buckhaults. She asked the FDA for their response on this DNA contamination. I expect it is the same as any other regulator. Absolutely disgusting and criminal. Something so significant, so potentially devastating to human health, including that of the jabbed person’s offspring, and they’re completely disinterested!
”I presented the findings of Buckhaults and McKernan to the US FDA.
I asked the FDA if it had begun an investigation into the issue of DNA contamination and whether it would review its guidance to industry about residual DNA in vaccines.
I also asked the FDA if it had instructed Pfizer and Moderna to conduct further testing to demonstrate the absence or presence of genome modification and whether it would issue new warnings to the public about the potential risks, now that DNA contamination in the vaccines had been established and replicated.
The FDA responded but did not answer specific questions, nor did it acknowledge the problem of contamination and potential safety issues. In a written statement it said:

More from Dr Bhakdi et al here;
”In the vaccine production process, the plasmid-DNA templates must be removed from the generated mRNA before the latter is packaged into LNPs.. Otherwise, plasmids will also end up in the fat globules. McKernan discovered that this crucial step of removing plasmid-DNA had not been assiduously undertaken. Huge amounts of plasmid-DNA were found in packaged form that guaranteed their successful delivery to cells, where they would be able to function for extended time periods.
To top everything, contamination of vaccine batches with functional plasmid-DNA must be expected to be the rule and not the exception, because no cost-effective procedure exists to reliably separate mass-produced RNA from the plasmids. The introduction of a foreign chromosome equates with alteration of the genome. Long-lasting auto-immune attack on the cells is inevitable.
Integration of plasmid-DNA into the human chromosome must moreover be expected to occasionally occur. Myriad cellular functions can then be permanently disrupted. Malignancies may arise and life expectancy may drop.”

Dear down voters, I don’t get it. Do you think this stuff is made up by ‘anti-vaxxers’? Do you think that there is not DNA in these tested vials? Or do you think there is DNA but it doesn’t matter and it’s harmless? Or do you know it’s a serious problem but you’re paid peanuts by the industry to troll this type of thing? Are you just indoctrinated incurious sheep with your brains in your arse? Or are you genuinely scared of what you’ve put into your bodies and are in desperate denial? I’d love to know. .
I’d go for the latter… Its going to be an extremely difficult thing for them to come to terms with, many most likely never will take the step to the other side…
“are not defined as gene therapy”
Are not defined as vaccines either
Are not defined as safe either
Are not defined as effective either
“When I use a word” said Humpty Dumpty in a rather scornful tone, “it means just what I choose it mean neither more nor less “
I wonder if someone on here could explain what exactly is DNA contamination and why or how it is harmful?
That’s a very good question. The article WHO has a recommended level for it so one presumes that having too much is bad (though it feels odd to be citing the WHO as a reliable source of information).
I’m just guessing here but the DNA is obviously going to be foreign to your body, presume that having alien DNA in you might interfere with things – maybe RNA doesn’t change your DNA but other DNA can merge with yours and start to make the cells you are manfacturing in your body be different to how they were meant to be?
Seeing as I’m obviously on ‘spoon-feeding duty’ this morning, this one is especially for you. Hope this is as clear as a bell.
”Buckhaults explained how two different manufacturing processes were used to make Pfizer’s vaccine.
The initial production of Pfizer’s covid vaccine used a method called Polymerase Chain Reaction (PCR) to amplify the DNA template that was then used for production of the mRNA. This method, called PROCESS 1, can be used to make a highly pure mRNA product.
However, 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” (circular DNA instructions), 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.”

Thanks Mogs

Why don’t you just read the substack I provided above?
You know that mass produced covid vaccine is cultured in E Coli, a bacterium which contains additional plasmids – bits of highly manipulable bacterial DNA – you don’t want. Especially when it’s packaged in attractive LNP (fat) globules specifically designed to cross cell membranes. But the production process is so bad it gets left in and TPTB don’t care.
Think Fatal Attraction. Dan only wanted Alex, a readily available woman (spike protein) in sexy, glamorous package (LNP) for a brief, no-strings fling (keep covid away) but ends up with the whole package of psychobitch from hell (additional plasmid) who destroys his life (et voila).
Hence the rise in sudden boiling of otherwise healthy bunnies that the mainstream press continue to ignore…
I get the analogy.
But my body is exposed to other DNA all the time and deals with it.
I’m still searching for an explanation for dummies of what is especially bad about residual DNA material in jabs and what exactly it does to the body that makes it dangerous.
Yes, your body is exposed to DNA, but it’s not being injected into the control centre of your individual cells. The LNPs in the jabs enable stuff to get through the cell membrane, which normally would be kept out.
Once DNA has been aided into the cell, there is a chance of it messing with your own code and stuff being activated or deactivated that results in bad news for health. Like a computer virus being injected into your application code and deleting data or corrupting it.
Also, the blood stream is not supposed to have chunks of E coli DNA in it, I think this is where the endotoxins sudden death reaction comes in.
Thanks
Makes sense
I think this explains what you want to know?

…for reference this is the “possible” problem with the SV40 promotor
“The polyomavirus simian virus 40 (SV40) is a known oncogenic DNA virus which induces primary brain and bone cancers, malignant mesothelioma, and lymphomas in laboratory animals. Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen. A meta-analysis of molecular, pathological, and clinical data from 1,793 cancer patients indicates that there is a significant excess risk of SV40 associated with human primary brain cancers, primary bone cancers, malignant mesothelioma, and non-Hodgkin’s lymphoma.”
SV40 got into humans from the early vaccines, back in the day when they cultured the potions in minced monkey organs. There was an epidemic of childhood leukaemias in the 1960s from the multiple jabs that were introduced. SV40 has been in the literature for decades, finally coming to more mainstream attention.
Another one is parvo in dogs, introduced by the first pet vaccines, another successful cross species transfer.
Pharma profit seeking potions, b*ggering your health for 200 years now.
Thanks all.
Must have been the late shift on down ticking duty.
Didn’t mean to give this a thumbs down but rather a thumbs up
If one digs extremely deeply … The 1918-20 Spanish Influenza pandemic death rate wasn’t soley caused by the “virus” .
I’ve put virus in apostrophes as I question “germ theory”
No jabs = fewer concerns.
