evidence: "EMA has seen no evidence of an association between mRNA vaccines and adverse events that could be linked to the presence of DNA material, nor are we aware of any scientific evidence showing that the very small amounts of residual DNA that may be present in vaccine batches could integrate into the DNA of vaccinated individuals," the Amsterdam-based agency wrote in an emailed statement. The Food and Drug Administration, which regulates vaccines in the U.S., echoed the sentiment, saying no safety concerns about residual DNA in COVID vaccines have been identified, despite more than one billion shots being administered. [...] "There is no evidence to support claims that the Pfizer-BioNTech COVID-19 vaccine contains plasmid DNA that could potentially impact a person’s DNA or be a theoretical cancer risk," the company wrote, referring to DNA materials used to trigger an immune response during vaccine development.
