Does insulin need to be stored refrigerated? I would have thought with the number of people dependent on it, they would have found a more resilient solution by now...
Heh. I'm not diabetic, so I don't know about all possible formulations. We had to give our cat insulin for a few months (until a pancreatic inflammation - thankfully - resolved), and we accidentally ruined a vial by leaving it out of the fridge overnight. I have also read about emergency deliveries of insulin during power outages - eg, after hurricanes. So, I hope you're right, but at least some insulin (maybe just the cheap stuff?) requires refrigeration.
As I understand the article this isn't about luxury food, but about medical samples.
