There are other factors at play in addition to the spike protein and mRNA. The covid injections from Pfizer and Moderna both contain SV40 promoters and have DNA contamination.
Microbiologist Kevin McKernan pioneered research on testing some of the covid vaccine vials and discovered unacceptable levels of double-stranded DNA plasmids floating around. This is DNA contamination. He found the contamination in Pfizer and Moderna vials.
During an interview with Peter Sweden, Sasha Latypova said that DNA contamination is “a huge problem because this is replication competent plasmid, it can then invade human cells, it can invade the bacterial cells that live in your gut. So, they go into the bacteria they replicate there, they replicate antibiotic-resistant genes…it can cause sepsis, it can cause cancer, all sorts of issues.”
The World Council for Health (“WCH”) stated that a red line has been crossed. “DNA contamination of mRNA ‘vaccines’ poses a risk to everyone on the planet,” WCH said.
“Replicable DNA, so-called plasmids, in both the monovalent and bivalent vaccines, which should not be there at all … We can only speculate how it will end, but what needs to happen today after the publication of the paper by McKernan et al (2023) is an immediate stop of the ‘covid-19 vaccine’ program.”
In Pfizer’s mRNA injection, McKernan also discovered Simian Virus 40 (“SV40”) promoters which are tied to cancer development in humans. He emphasised that the SV40 found is a viral piece, it is not the whole virus. However, it still presents a risk of driving cancer.
SV40 or Simian Virus 40 was the 40th virus found in rhesus monkey kidney cells when these cells were used to make the polio vaccine. This virus contaminated both the inactivated polio vaccine (“IPV”) and the oral or “live” polio vaccine (“OPV”) developed by Dr. Albert Sabin.
