On: No one who got Moderna's vaccine in trial developed severe Covid-19

no. DNA doesn't synthesize proteins.

Roughly: Protein descriptions are "read" from DNA into mRNA, which is then used by ribosomes to synthesize proteins. An mRNA vaccine adds additional mRNA with instructions to synthesize the vaccine-specific protein to the cells. So it uses some of the same mechanisms that are also used to generate proteins from DNA, but does not involve DNA itself.

Right. This process happens outside of the nucleus of the cell.

Perhaps people are getting mRNA vaccines confused with CRISPR, which _is_ a technique to modify DNA.
