Sure. mRNA vaccines didn't emerge spontaneously during covid. They were studied for many years before, which is why they were so readily available for covid. Just because you never heard of their existence prior to covid doesn't mean they weren't the subject of intense study. The first mRNA vaccines were tested on mice in the 1990s, and on humans in 2013.
