Correct, but it is the mechanism of exactly how this is done that needs further explanation. People are nervous that these mRNA's are getting into the nucleus and altering their DNA. And I keep reading that is not what is happening, although I don't have a good explanation as to why not.
My understanding is the cell nucleus 'aquires info' from the RNA to produce a 'Spike Protein'. The spike protein is what is critical to the immune response. Is the cell DNA being 'altered' during this process? I think that is the central fear that people have.
