--

A century after its discovery, insulin remain essential in treating diabetes, and has a relatively low production cost, with a vial generally costing less than $6 to make.

Kiah Williams takes a look at the US supply chain to explore why medications are so expensive.

Lesson by Kiah Williams, directed by Tolga Yıldız, Serin İnan, Kozmonot Animation Studio.
