It's definitely possible. In the mid 90s had friend who worked for Chiron Diagnostics (now Novartis Vaccines). He designed some parts of their newly built flu vaccine production line. This was a building sized machine with 60 "lines" to run vials through in parallel and could run 24/7. As I recall though only a few lines were ever run at the same time with the others as backups if needed. But, they all could be put in play and if so it would produce well over 1 billion vials per year. Again, this was in the mid 90s. And now I wonder... how far back was this planned?
