That's really not how mRNA works. If DNA is the source code of our body, then mRNA is the machine code that exists in L1-instruction cache. (There's another process out there that copies DNA into more readily processable RNA) The way any of this mRNA stuff works is by throwing instructions into our body to create certain proteins in certain configurations. For COVID19, the vaccine is... as XKCD-put it... a set of blu…
I believe there are also viruses who can insert themselves into the cells DNA, and there are some articles on how some parts of human DNA is already old virus genome. Viruses are far more dangerous in that regard.

Not necessarily. "Corrupt DNA" can be somewhat detected the body as a cancer cell. Our "Natural Killer" cells then kill those cells.
Cancer / corrupted DNA happens all the time in our bodies. Even healthy bodies (!!). The difference between a cancer-patient and us however, is that a cancer-patient is overrun with cancer-cells.
Our bodies naturally kill off cancer under normal circumstances. Figuring out why cancer / corrupted DNA completely takes over the body is a big mystery, especially because our body is so good at fighting off cancer under normal conditions.
