If Pfizer and Moderna can do that from a finished vaccine, I suppose their competitors can too.
Pfizer had never done vaccine research the same for Biontec. The Pfizer crap can contain up to 30% random RNA so you get a random gene therapy. Pfizer is part of the dark empire that kills people for money. Pfizer indices 5x more often immune suppression than Moderna that at least tried ti emulate a kind of vaccine.
But only full blown idiots use the spike RNA in a gene therapy.
