I have not got around to finding out all the details or discussing the mechanisms, but someone on another forum asked me "how the new vaccines work?" and I hastily put this summary of the cells and vaccines together. Do I need to correct this for those few people?
Quote:
The mRNA is delivered to the blood stream and reaches circulating immune cells, that then manufacture the viral protein.

The viral like particles infect the number of cells in circulation that they can. They do not produce more virus or more of themselves. Once the vaccine is gone, the new immune cells produced in the bone marrow

do not get the vaccine induced spike protein.
The immune system has to learn to respond to this spike protein in the time that the vaccine particles are active and functional.
