Earlier quoted context omitted.
That is one of the dumbest possible interpretations you could make from those references. The point was to show (to unfamiliar readers) that there exists plenty of mechanisms by which RNA -> DNA could happen, and it has been extensively studied and characterized.
That’s just misrepresenting. While there exists pathways for RNA->DNA, they are a niche occurrence happening on evolutionary timescales. It is not at all applicable to the 30 minutes of mRNA half-life of the vaccine. And even just playing with the idea of our genome having the spike protein’s gene, it would either just sit there doing nothing (remember it is injected into muscle tissue) or get expressed. The former c…
I think you'll find it's much longer that that for the vaccine. Apparently it hangs around about a week. The mRNA is modified to last longer than natural mRNA.
