Thanks for sharing this. I learned a lot from watching this video and I have another channel to subscribe to now :) One thing that I found interesting was how they identified today's announcement of the BNT162b2 vaccine candidate (back in September) as one that would require the massive investment in cold chain infrastructure. They also highlight Pfizer's engineering of a separate series of cold boxes that would keep the vaccine at temperature for up to 10 days, thereby enabling it to be shipped through standard logistics networks. Great stuff.
