It seems that according to these papers, if there was vaccine mRNA in the reproductive tract immediately prior to or immediately after fertilization, then theoretically the spike protein could possibly get integrated into the offspring’s genome. But how could the vaccine mRNA end up in the reproductive tract? Seems unlikely. It’s intramuscular, not in a vein. The implications of sperm-mediated reverse transcription are quite unsavory regardless.

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.

  The context is a guy claiming the mRNA vaccines will create a “humanoid race” with no evidence and everyone rushing to the other side and saying there’s no situation where exogenous RNA can ever be integrated into the genome, also without evidence. I doubt anything like this occurs with the mRNA vaccines, but you helpfully exposed this dialectic with the links.

  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 case would cause no problem (no descendant would inherit it as the gonads are not affected), and the latter would be trivial to see with a continuous immune response.

    >the 30 minutes of mRNA half-life of the vaccine. 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.

      There is still an awful lot we don't know about cellular biology, so I'm always a bit baffled when people that should know better say that this or that is (virtually) impossible. Fortunately, we're running the largest phase 4 clinical trial in human history, so in 25 years or so we'll have some absolutely great longitudinal data.

        mRNA is continuously produced by every living cell in your body. How come then that you don’t get ridiculously many duplicated copies of the created mRNAs, something that only happens at an evolutionary timescale? You have multiple orders of magnitudes more naturally created mRNA, why isn’t there a concern for that?

        how do you know what is produced and called "just mRNA" is the exact same kind of thing that is the mRNA in your body? You can test to verify that it has all the characteristics of mRNA. However, you obviously can't 100% confirm that it does not have characteristics that is not in "natural" mRNA, since the list of characteristics mRNA does NOT have is infinite.

        What do you mean produced? As in the pharmaceutical factory? You can quite literally have a look at it with an electron microscope, and there are trillion other ways to chemically verify that. Also, we can reprogram bacteria to manufacture any protein for us - molecular biology is very advanced. Why do you feel the need to question very basic “problems” that were more than certainly thought about and solved by the many experts working on it for decades? You can question whether the engineers of a car engine though of heat dissipation but you would find it sort of dumb, wouldn’t you?
