It is also quite cheap, which as well as needing less refrigeration boggles my mind why the EU sat on their hands for 3 months trying to negotiate down an already cheap cost. $140 billion to vaccinate the world is not a large cost, and many nations will choose (have chosen) their own solutions, for the remaining, perhaps $60bn, that's not a large amount for developed nations to pay compared to the costs of reduced trade and potential further mutations, that's $60-$100 per person in developed countries in cash, or more likely however countries want to amortise that.
