I've said above, if there aren't other treatment options available, it makes sense, but even then I don't know why one wouldn't use standard immunotherapies instead, which are less risky.

I think Moderna and Pfizer generated a lot of profit from the vaccines, and now they need a way of turning that over into capital, and they are still trying to find ways to have widespread adoption of regular mRNA treatments. But even millions or billions of dollars of capital investment will not yield a profit if its a bad investment.
