Is there some kind of document in an informal whitepaper format that explains how the mrna encapsulation works and how its manufactured? Anyone can copy paste a piece of mrna but afaik the magic happens with the delivery mechanism/membrane/structure.

I haven’t searched for the Moderna one, but for the Pfizer I have these two links:
