>I am not a scientist, but I would expect that the mRNA vaccines would have less of a chance of having an auto-immune reaction since they contain only one of the many proteins contained in the actual virus.

This is the angle that, for me, is suppressing my innate concern for a widescale and rapid application of a brand new immunological therapy. It's extremely targeted and feels like the future. I can imagine a day where the FDA approves the process rather than the instance of mRNA-based therapies, allowing for highly personalized treatment.
