The question is, how did this start just now? In 2020? How is the COVID-19 vaccine the first to use mRNA? Anyone with who has taken AP Biology could conceive of and understand the idea behind making vaccines rapidly: take some mRNA, inject it, have in translated as the antigen in the body. Poof, that's it. I feel like the development of mRNA drugs should have started in the 70's or 80's. It isn't exactly high-tech or clever.
