MHRA has responded to my email questions about the origin of the genomic sequence from which the material known as mRNA in the Pfizer BioNTech #vaccine derives.
I quote:
"The DNA template used does not come directly from an isolated virus from an infected person."

& "The DNA template(severe acute respiratory syndrome coronavirus 2, GenBank: MN908947.3) was generated via a combination of gene synthesis and recombinant DNA technology."

I had to push hard to get the answer I wanted.
I had to know if the mRNA is genuine or created by a computer program. All evidence pointed to there being no isolated #SARSCov2 virus anywhere in the world.
Given our recent experiences with computer "models" -

Can we trust this?

When I read the Wuhan study in Feb 2020 I was mortified by the monkey kidney & foetal cell-lines which were used as a "culture" before rt-PCR amplification. Isolation was never satisfactory at any stage thereafter.
I honestly felt sick.
The genome sequence was computed from this.
