I thought it would be interesting to look at the history of mRNA vaccine technology.
The earliest publication of mRNA vaccine potential I could find was published in 2012. It used mouse models.

Work continued on this technology, and the first human trial was done in 2017. It was for rabies, whose currently approved vaccine is reportedly extremely painful and expensive. It contains egg, which is a major allergen. It also costs $1000-2000 which is a lot compared to Tdap, which is around $57. So a less expensive, efficacious vaccine was being looked at with this new tech.

Major publication on mRNA technology was done the following year in 2018: "mRNA vaccines-a new era in vaccinology". This paper discussed things like how lower costs and ease of manufacturing of mRNA vaccines compared favorably to older vaccine technology. How mRNA could stimulate a wide range of immune responses, involving B as well as T cells. It mentioned how, since the rapidity of initial SARS and MERS infections emerging just a few years previously, a newer tech that could be manufactured & distributed at much less expense was needed for these new rapidly emerging viruses. It stated "the development of more potent and versatile vaccine platforms is crucial" because the older tech took a lot longer to develop & manufacture.
It also mentioned the potential for mRNA tech to make anti-cancer vaccines.

So this tech has actually been in the pipeline at least a decade. The first human trials were 2 years before Covid-19 came along. I don't know why THIS type of information is not being widely publicized. Perhaps we should start writing our politicians and news media, requesting they disseminate the information.
