Nice explanation.

I still think it is a bad idea to let mRNA alter the genetic instructions of a cell to produce virus like substances. This is basically exactly what a virus does (but they also program the cell to copy the DNA) and super unnatural. And there is nothing that the body can do to stop this if it goes wrong.

Your body also cannot stop the nano particles, they stay in your system and continue scratching holes in your body cells. If the mRNA can enter the cells via those holes, what else can?

And you are at complete mercy of those who create the mRNA. And we have all seen how untransoarant that was.
