DNA Contamination in Pfizer COVID Vaccine Exceeded 500 Times Allowable Levels

A new peer-reviewed study raises concerns about the methods used to test for potential DNA impurities in the Comirnaty COVID-19 mRNA vaccine produced by Pfizer and BioNTech.
In the study published this month in Methods and Protocols, German researchers Brigitte König and Jürgen O. Kirchner questioned the reliability of the quantitative PCR (qPCR) technique Pfizer-BioNTech used to measure DNA contamination in the vaccine’s active substance.
The researchers experimented with dissolving Comirnaty’s lipid nanoparticles. They found DNA impurity levels ranging from 360 to 534 times higher than the 10 ng (nanogram) per dose limit set by regulators globally.
