While development of a new vaccine-delivery platform is exciting, I think it's important to take this announcement into perspective. The main problem with producing vaccines is not principally the delivery platform, but the difficulty in generating a sensitive, specific, and effective immune response to your target bug. This problem has plagued immunology for decades (and is a bit of a black art), and sadly may not be solved simply by using mRNA. Nevertheless, promising news. Presumably this is funded at least in part by the significant profits Modena has generated from the COVID vaccine.
