Read these reports with a jaundiced view, yes the process used in the clinical trial was small scale, batch manufacturing with less contamination, whereas the recombinant e.coli mass production process did introduce plasmid DNA & other contaminants, HOWEVER…these are not the main reasons that the mRNA vax technology has resulted (& will continue to result) in such great death and destruction, it is how the technology is designed to work & what it commands patients' bodies make that are the real drivers of damage
Don't let this be a scapegoat whereby mass mRNA vaccines are rehabilitated "by just cleaning up the manufacturing process"
