“How long does this go on?”
The mRNA lasts 72 hours after which they disintegrate. The adaptive immune systems takes about 2 weeks to create antibodies to the spike proteins. The mRNA does NOT cause any genetic mutations. They don’t even enter the nucleus where the genetic material is.
It would take 2 weeks for IgG, but I have seen no evidence that the foreign viral m-RNA disintegrates.
Correct. It does not enter the nucleus and mRNA disintegrates very quickly...it does not hang around.
I think some people are conflating this with the Astrazeneca vaccine which is not approved for use in the US...that one actually does send things into the nuclear membrane. That gives me pause, as that could influence the cell permanently - I don’t know that science on that, but what if cell while having the material reproduces through mitosis? What would the long term effect of that be?
