Comment on Exploring the Supply Chain of the Pfizer/BioNTech and Moderna Covid-19 Vaccines

Comments

The most mind boggling fact for me is that glass vials are a bottleneck.

We have all these high tech stuff, $50k a gram chemicals, custom built machines, DNA printers and nano-scale technologies producing a substance where every atom is at the right place.

And all that is produced at a scale where we are limited by glass vials. That's literally ancient technology, and commodity stuff. Ok, it is a bit fancier than what the Romans had, but these are still just glass bottles.

The glass vial part is expected, things get complicated when multiplied by a billion, but it gives a sense of how much vaccine is being produced and how fast it is done.

But the blog post states that preloaded syringes are the bottleneck and that's why they are using glass vials?
