Having something is different than having something at scale and being able to effectively implement it. Logistics in less developed countries is already more difficult. Adding in specialty refrigeration requirements further complicates that. Large scale logistics should never be assumed or hand waved away. Mass toilet paper shortages in first world countries this year is a perfect example of how easy it is to massively disrupt logistic chains. What do you think shipping 100 million plus vaccines a month that require specialty refrigeration and dry ice will do to the supply of dry ice in Nigeria or Albania? Or the US for that matter? How many of those dry ice shipping containers does Pfizer have? How quickly can they be manufactured?
