That's what I'm curious about too (just an engineer with no medical degree). There are a lot of viruses that are simply undetectable by our immune system so it never triggers a response (similar to cancer). A good example is the herpes family. I was under the impression that you can't fully cure herpes because it hides in your nerve cells. I wonder if mRNA can force an immune response to cure this.
