This is not how protein expression works. When a cell starts making a protein from an mRNA sequence, it doesn't just keep doing it forever. There are tens of thousands of proteins being produced in the body from their corresponding mRNAs, and this requires a strict and complex system to get the relative amounts of each protein required at any given time.
A critical part of that control mechanism is that cells don't just keep expressing an indefinite number of copies from a single mRNA. A lot of this comes down to a section of the mRNA we call the 3' untranslated poly A tail. As the cell runs off copies of the protein, this poly A tail shortens. As it shortens, the mRNA becomes less stable, and a cascade of processes in the cell mark mRNAs with shortened poly A tails as essentially "finished", triggering their rapid breakdown into short fragments, and a halt to expression of the protein they encode.
In simple terms, an mRNA molecule is an instruction to the cell saying "make me a batch of this protein." The poly A tail and related mechanisms serve as an instruction for how many copies of the protein are in that batch. Once complete, production of that particular protein halts, and the mRNA is broken down - a finished instruction. mRNAs are not instructions to just make a protein forever - such an instruction would be by its very nature cytotoxic, if you could come up with a way to bypass all the mRNA regulation systems to create such an instruction.
Just to avoid any confusion, the fragments detectable up to 28 days post vaccine above are not usable instructions for the cell. The mRNA needs to be complete and unbroken from its 5' UTR to at least part of the 3' poly A tail to get any intact spike protein produced. They resemble the fragments you get after an mRNA instruction is "finished" and degraded. Since these fragments are detected free in the blood plasma, it's actually questionable if the mRNA molecules they are from were ever taken up by a cell and expressed at all. It's more likely we're seeing the remains of the fraction of the mRNAs that didn't make it into cells in the first place. The surprise is that the bits are big enough to still be identifiable, rather than degraded all the way down to their individual bases.
Another point of confusion here. The spike protein doesn't stay in the cells once expressed. Another section of the mRNA - a sequence termed the S glycoprotein signal peptide in the 5' UTR - serves as an instruction for what to do with the protein as it's produced. Both the Pfizer and Moderna vaccines contain the instruction to export the spike protein out of the cell, so the immune system can see it. If the protein stayed inside the cells, the immune system would not be able to target it. Nor is the immune system going to target the cells just for expressing the spike protein. Unless the cells begin malfunctioning to the point that it's detectable via the various intercellular signaling methods.
Clearly you have not read the Moderna and Pfizer papers.
The cells that take in the mrna do produce protein and as a consequence are attacked by the immune system and destroyed. If they are not then the vaccine is malfunctioning even worse than we already saw. The selling point of the modified spike protein encoded in the mrna used was that it would be 'anchored' to the cell membrane but exposed. This inevitably drawing an attack and ending with apoptosis. One possible problem is that this does not necessarily avoid the protein at that stage getting loose and wrecking some more havoc before being destroyed.
To be clear:
I'm accusing you of deliberate misdirection. You use a lot of terms to pretend you're being technical but you are attempting to distract from what really goes on. And I do not thing you ever argued here about the covid and pharma iindustry issues in good faith. I know when I see certain types of attempted manipulation. It's not accidental.
Some basic questions, are you willing to answer succinctly and in plain language?
What exactly happens to the produced protein? To be specific, where exactly does it move into after being produced?
Do you agree or do you deny that it is supposed to moves into the cell membrane and gets exposed to the outside of the sell, but anchored to the cell that produced it?
What is supposed to happen to that cell when the immune system reacts to the protein?
And I'm worried that at least the people who liked your comment willfully choong ignorance rather than researching things
because checking things out might reveal to them uncomfortable knowledge. The embracing of ignorance in contemporary culture, for the same of some tribal sense of belonging to a side of any ongoing "polemic", worries me more than the covid! Facts are there to check and people refuse to check, refuse to see, and keep playing according to the "narrative" of the tribe they think they ought to belong to. There's some serious psychological/social breakdown going on...
Edited: I may be getting to harsh here. People are human, and subject to unconscious bias, professional bias, social influence, whatever.
But I am very, very frustrated at the attempts to not see the problems of this whole covid disaster, of what was done wrong.
