I believe the advantage of the mRNA method is that it’s somewhat generic: you can stick any (protein-coding) RNA fragment into it, and it will be expressed in the body and picked up as a target by the immune system if it has any potential for the latter (I. e. isn’t something that’s ubiquitous in the body already) As such, it is faster to get from idea to vaccine. Recent history is an example already, but the cycle will be improved dramatically considering the technology is very much still in infancy. It’s also cheaper, to the point that producing ten doses of ten different vaccines may not be more expensive than producing a hundred doses of a single vaccine. This will be helpful against “cancer” which is closer to an unlimited number of different diseases than a single target.
