Just to correct or to clear, the ribosomes are the vehicle in which mrna is used to make the spike protein.Normally mRNA is made in the nucleus of the cell(transcription), and then it leave the nucleus. But the mRNA in these vaccines, are produced in a lab. The lab creates a strand of genetic material. This strand enters the cytoplasm of the cell, and begins coding for the viral spike protein(ribosomes)
So not sure what the fear is. unless you suspect that there is more to the mrna - like big corporations have chucked extra "recipes" in it and you are paranoid about it. Whether the spike proteins came from your cells or from the standard "produced from infected cells outside the body, like chicken eggs".... big deal?
