The virus goes on to do EXACTLY what it's trained for - it puts that DNA into the cells of people it "infects". Only it no longer knows how to make us sick, because we took away its DNA. Instead, it does a very thorough job of doing exactly what we wanted, putting our gene in a cell and triggering expression of the protein we wanted.
