evidence: Factually inaccurate: Health Canada stated that it was aware of residual DNA in COVID-19 mRNA vaccines before the vaccines were authorized. A dossier submitted by BioNTech to the European Medicines Agency in 2020 also showed that data on residual DNA was made known to the regulator. [...] 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.
