Lots of pharma companies are working on an mRNA COVID vaccine but besides being a COVID vaccine what does the mRNA part signify? I know that like DNA vaccines it's supposed to get your own cells to make antigens instead of introducing them but what is the production process for mRNA vaccines?
Is it made in tiny petri dishes inside a biohazard containment unit or can it be made in flasks in a minimal containment environment? Can it be made in large quantities by unpaid biology undergrads in labcoats hunched over desks like a textile sweatshop? Can it be made in a vat with yeast?
