Recent studies by Kevin McKernan, a leading expert in sequencing methods for DNA and RNA, have revealed that batches of the modified mRNA vaccines produced by both Pfizer and Moderna contain a high proportion of contaminating bacterial DNA. In all, the DNA accounts for up to 20-35% of the nucleic acids contained in each of the vaccine batches. These alarmingly high concentrations far exceed the levels deemed safe by standard-setting organizations such as the European Medicines Agency (EMA). This document summarizes the evidence of that DNA contamination and discusses what possible health risks it implies to the recipients of the vaccines.
