MHC- *stands* for major histocompatibility complex, so what you said is about as awkward as saying "HIV-virus"...
After the mRNA delivers instructions to the immune system,
The mRNA doesn't deliver *anything* to the immune system. It goes to the ribosome, inside the cell, where its codons are translated into spike protein.
and the spike cells that might remain are tracked down and eliminated.
The spikes aren't even cells. They are artificially designed and modified protein molecules.
You keep on talking way the Hell over your head and it shows.
MY mistake: “Spike molecule”—I meant the Spike Protein.
Yes, my terms for the “MHC-1 and MHC-2 complex molecules” are how I heard them described, not knowing what the acronym stands for. You are correct.
I should have written that Messenger RNA (mRNA) vaccines teach our cells how to make a protein that triggers an immune response. My words, “the mRNA delivers instructions to the immune system,” was a poorly written short hand for that process. Sorry. You have gained my respect for you.
By the way, that video I linked to you tells it far better than I could. Did you check it out?
