The exciting thing with mRNA vaccines is that while developing the delivery platform took decades, developing the COVID vaccine itself was just 48 hours according to the CEO of both Moderna and BioNTech. Right now they have a lot of work with manufacturing (and they had lots and lots of paper work to do), but even there I think they are doing great, as they were not prepared for a pandemic.
As the drug delivery platform is working great, it seems like it can be reused (unlike with older platforms), and the hardest part of developing new mRNA vaccines is to research the genetic code to put in it.
