The money sentence: “Notably, the authors commented that for the Pfizer product, the higher the level of DNA fragments found in the ‘vaccine’, the higher the rate of serious adverse events.”
From Maryanne Demasi at brownstone.org:

The recent findings of DNA fragments in the Pfizer and Moderna Covid-19 ‘vaccines’ has led many to question why the FDA, which is responsible for monitoring the quality and safety of the ‘vaccines’, has failed to sound the alarm.
For years, the FDA has known about the risk posed by residual DNA in ‘vaccines’. Its own guidance to industry states:
“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.”
Put simply, the FDA acknowledges the possibility that fragments of DNA left over by the manufacturing process can be incorporated into a patient’s own DNA, to potentially cause cancer.
FDA and WHO guidelines consider the amount of residual DNA in a single dose of traditional ‘vaccine’ should not exceed 10 ng (one billionth of a gram).
But this limit – used for traditional ‘vaccines’ – is unlikely to be relevant to the mRNA ‘vaccines’ whose lipid nanoparticles can penetrate inside cells to deliver the mRNA efficiently.
A recent preprint paper by Speicher et al analysed batches of the monovalent and bivalent mRNA ‘vaccines’ in Canada.
The authors found “the presence of billions to hundreds of billions of DNA molecules per dose in these ‘vaccines’. Using fluorometry all ‘vaccines’ exceed the guidelines for residual DNA set by FDA and WHO of 10 ng/dose.”
Speicher et al also reported finding fragments of DNA larger than 200 base pairs (a measure of the length of the DNA) which also exceeds FDA guidelines.
