A study published in the journal Science, Public Health Policy and the Law found that DNA contamination in Pfizer’s COVID-19 vaccines far exceeds legal limits by three to four times.
Researchers identified “large amounts of DNA after RNase A (Ribonuclease A) digestion in all lots with concentrations ranging from 32.7 ng to 43.4 ng per clinical dose.”
“This far exceeds the maximal acceptable concentration of 10 ng per clinical dose that has been set by international regulatory authorities,” they wrote.
“Of note, official limit values for residual DNA in biologicals are defined for antibodies, attenuated vaccines, and protein solutions, but not for RNA injections and – even more important – for nucleic acids packaged in transfection reagents like lipid nanoparticles, which were used for the first time in the COVID-19 injections,” the researchers stated in the study. “In fact, no scientific evidence exists that would permit a safety level of residual DNA to be defined in such injectables whatsoever.”
The researchers also found the “presence of a DNA sequence of the SV40 promoter/enhancer” which was “not declared in the plasmid map that BioNTech/Pfizer submitted in the approval procedure.” The SV40 promoter/enhancer is the mammalian Simian Virus 40.
“This finding is very surprising and raises the legitimate question: Why did BioNTech/Pfizer apply this totally unnecessary but highly dangerous element in their plasmids and use it as a template for the production of modRNA?” the study’s authors wrote. “In our opinion, BioNTech/Pfizer must be held accountable for incorporating this highly dangerous element in their plasmids.”
The study concluded by calling for an “immediate halt of all RNA-based biologicals.”
