Dr Mercola, at now deleted post, gives an excellent overview of the Covid vax DNA contamination scam. In a nutshell, microbiologist Kevin McKernan found massive DNA contamination in Pfizer’s and Moderna’s Covid booster shots, with the level of contamination reaching up to 30 percent. None of this contaminating DNA should have been there at all, and its presence increases the risk of the DNA being integrated into the cells, and ultimately causing cancer. It is known from experiments in a test tube that the MRNA of the Covid vax can enter human liver cells and reverse transcribe into DNA in as little as six hours. The concern is that if the mRNA is integrated into the DNA, that the effects could be passed on to future generations, if any.
Simian virus 40 (SV40) promoter has also been found in the mRNA vax, further increasing the cancer risk.
