Thank you for the response. This makes sense. As for the second segment. I only have more questions now. Could it be that requesting that the cells produce additional proteins of a particular kind "overloads" them or simply "asks too much" in a fashion similar to a virus? That seems unlikely unless the administered medication is simply "too much". I wonder, is there a saturation point? ie a point where additional mRNA medication does not result in more cells producing the target protein? Seems likely. Which then raises the question, if such a saturation point exists, then what is causing cells to explode due to virus replication? Is it that the viral particles can not escape the cell and thus they "use" pressure? If so, have we encountered a virus that "opens up" a cell without damaging it and eventually becomes parasitic to the host? It's probably the case that when cells die prematurely, they leave traces for our immune system to trigger an issue, so not destroying the cell seems like a beneficial evolutionary advantage. Otoh, the additional code required for this is likely very "expensive". I hope a virologist drops by and clarifies on this.

It could be. I believe that most of the cells that express from the mRNA vaccine do indeed die (from the immune response against them). I'm not positive about this though.
