Dr. Kevin McKernan revealed that the Pfizer COVID-19 mRNA vaccine used in early trials was not identical to what was ultimately distributed to the public. He claims the original PCR-based DNA template was replaced with a larger plasmid DNA, introducing SV40-related genetic elements that were not disclosed in trial data. These added DNA fragments, he explained, carry more inflammatory epigenetic signatures that could influence the immune system’s response. McKernan also criticized the widely publicized “95% effectiveness” claim, noting that the data reflected only relative risk reduction, not absolute risk—and that the formulation tested was different from what millions actually received. He urged independent genomic sequencing of vaccine vials, arguing that unresolved contamination concerns highlight a broader failure of transparency and scientific accountability.
