The mRNA vaccines being tested may need down to -70°C cold storage during transport and immediately before use, so quite a logistical challenge. Prioritizing those most at risk will be critical to knocking down the CFR dramatically.

- bluGill 6y agoLiquid N2 is common in industry. There are national and local companies with branches scattered all over the US that can supply liquid N2 to anyone equipped to handle it. Since doctors use N2 (to freeze warts) they know how to deliver medial grade N2 (if there is such a thing). Those suppliers will work with their normal customers to ensure medical use gets what they need (if arranged in advance they can produce less in exchange for a vaccine for their employees which ultimately means better profits) That is N2 isn't a supply problem. However there are other logistical problems. Most industry uses of N2 are in very large quantities and so the ability to fill a millions of vial sized containers of N2 might not exist even though more than enough N2 exists.
