I think they are using the SV40 promoter because it affects transcription in E Coli. While SV40 is commonly used as a promoter for eukaryotes/mammalian cells, it is known to act as a promoter in E Coli and other prokaryotes. Side note: The downstream gene, AmpR, does not do anything in mammalian cells anyways because mammalian cells are naturally resistant to ampicillin (Amp) and kanamycin (Kan).

Given the high level of engineering in the plasmid (both Pfizer and Moderna are well aware of the interaction between custom T7 polymerases and the T7 promoter in the plasmid), it is likely that the choice of and location of the SV40 promoter is very intentional. Pfizer has the experts in this field and know why it's in there. It also appears that they told regulations that it does nothing in the production process- that seems unlikely because they could simply remove it without affecting production.

Moderna uses an engineered T7 polymerase: https://s29.q4cdn.com/435878511/files/doc_presentations/2022/05/Science-Day-2022-Master-Slides-FINAL-(05.17_7am).pdf

Politically, it seems that US regulators are operating by a new set of rules where they allow more unsafe products onto the market. This gives them leverage against pfizer, moderna, etc. It's like a mafia extortion racket where the mafia threatens to burn down your business unless you pay them; however, they need business owners to have businesses that are flammable.

thank you again, Kevin

this morning (my time, Australia) saw the release of an interview with Dr John Campbell on YouTube, where we specifically discussed your findings (et al) and the actions of the regulators, particularly in the context of these modRNA drugs being legally defined as GMOs and Gene Therapies, now with added DNA contamination .. a small step further in raising global awareness
