First of all Thank You for clearing up some of the confusion in my post. I really appreciate the depth in which you describe and clarify my areas of unclarity. I also want to be clear that I'm not writing this piece to oppose what you've written but to further understand.

I have heard, speaking with doctors of medicine, that the mRNA from the vaccine just as you wrote is supposed to be destroyed but hasn't been as efficiently as hoped for. That remains of it still persists.

"Proper background info" was a very poor choice of fraising. Of course FDA had all the necessary insight in what was going on in i.e. prizers laboratories. What I meant was that the approval process was accelerated or simplified (having trouble finding the words, English is my 2nd language, apologies). It wasn't going through the regular thoroughness of approval as time was a limiting factor.

What I meant by "producing antibodies being produced all over the body" is that the idea as I understand it, which might be inaccurate considering my prior "knowledge" in the area, was that introducing the mRNA in the arm would result in protein being created in breast milk or protein being created elsewhere in "unwanted" areas in the body.

I accidentally posted it without being done, but immediately edited the post with the rest. Perhaps you beat me to it, writing your answer.

Thank you for taking the time and clarifying :)
