I would love it if somebody would post a more detailed explanation of the mRNA vaccine manufacturing process here on HN. The news media keeps mumbling vague terms like "ingredients", and it's frustrating. Conventional vaccine production is a highly biological process... chicken eggs being used to make the flu vaccines and so forth. I was under the impression that the mRNA vaccines are chemically much simpler -- just…

Okay, this is the best article of them all, the one I was wishing for. Congratulations, you win ten thousand Internets!
Best part (although the whole thing is totally worth reading):
As Neubert says, “Welcome to the bottleneck!” Turning a mixture of mRNA and a set of lipids into a well-defined mix of solid nanoparticles with consistent mRNA encapsulation, well, that’s the hard part. ... Everyone is almost certainly having to use some sort of specially-built microfluidics device ... These will be special-purpose bespoke machines, and if you ask other drug companies if they have one sitting around, the answer will be “Of course not”. This is not anything close to a traditional drug manufacturing process. And this is the single biggest reason why you cannot simply call up those “dozens” of other companies and ask them to shift their existing production over to making the mRNA vaccines.
