Further analysis by Dr. McKernan and his team has also confirmed that the plasmids are intact and capable of self-replicating, and that the relevant promoters are present that allow them to express mRNA for spike protein in human cells (and not just in bacteria).

This indicates that these DNA plasmids are likely to survive for long periods, be taken up by cells inside the body and induce the cells to produce spike protein for an indefinite period of time..

It is thought this could explain the observed persistence of spike protein in the blood of vaccinated persons for weeks or months after injection, which is believed by experts to be a contributor to adverse effects of the COVID-19 vaccines.
