evidence: Residual DNA present in the COVID-19 mRNA vaccine is a result of the process used to make the vaccine. The Pfizer COVID-19 mRNA vaccine is manufactured by mass producing the genetic material for the SARS-CoV-2 spike protein in the bacterium Escherichia coli. This is accomplished by placing the spike protein’s genetic material into a plasmid, which is a circular DNA molecule, which is replicated by E. coli. [...] It’s incorrect to claim that regulatory agencies were unaware of residual DNA in the COVID-19 mRNA vaccines until now, as the same document submitted to the European Medicines Agency indicated that residual DNA was among the impurities quantified by the manufacturer ("Process- and product-related impurities including host cell genomic DNA, RNA, proteins, endotoxins, bioburden and plasmid isoforms, for the plasmid DNA, are routinely quantified"). [...] In brief, the claim that regulatory agencies like Health Canada hadn’t known about residual DNA in COVID-19 vaccines or that vaccine manufacturers didn’t disclose the presence of residual DNA in the vaccines is inaccurate.
