how systemic are the effects of the mRNA vaccine? and, how long does the mRNA stick around for?
would it be practical to use regular mRNA injections to generate particular proteins in-vivo? as an example, the herpes simplex 1 resides in neurons for an extended time, and a method of evading detection is by interfering with antigen presentation.
by delivering mRNA into cells, and generating proteins inside the cells, you could perhaps deploy a protein to interfere with this "antigen blocking" mechanism.
of course, there are several caveats, and it would require finding a protein that does what i'm asking, but would that be theoretically possible with this technology?

what are other interesting applications?
