Study: DNA Contamination in Pfizer COVID Vaccine Exceeds 354 Times Allowable Limit

Fact checked by The People's Voice Community

The Pfizer-BioNTech Covid vaccine contains up to 354 times the recommended limit of DNA contamination, according to the findings of a peer-reviewed scientific study which raises concerns regarding the carcinogenic potential of the Comirnaty COVID-19 mRNA vaccine.

German researchers Brigitte König and Jürgen O. Kirchner found the DNA impurity levels in the vaccine were significantly higher than the limit set by regulators including the World Health Organization, raising concerns about the methods used to test for impurities.

The study also highlights serious potential risks associated with high level DNA contamination, such as insertional mutagenesis and the presence of cancer-promoting genes.

Kirchner first warned about the consequences of DNA contamination in the BioNTech vaccine in 2022 in the book Die mRNA-Maschine – translated as ‘The mRNA Machine’ – which he published during the pandemic under the pen name 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 meantime, 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.

Sott report: 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.
