The world's now scrambling for dry ice. It's just one headache in getting coronavirus vaccines where they need to go

 Another obstacle for the delivery of corona virus vaccines will be to keep them at the proper temperature.  The vaccines have to be kept at a super cold temperature, Pfizer's has to be at almost -100 F. This will pose a great stress on countries that do not have super cold refrigeration since it takes special refrigerators to reach these low temperatures. Some countries have no such type of refrigeration. Even for countries that do have the technology it will be difficult to manage the transportation. Rural communities will be the most impacted because it will be much harder to get cold cargo all the way into small villages or towns. A complex line of transportation has to be created in order to efficiently deliver the vaccine. Cargo shipments, to truck shipments, to delivering to local pharmacies has to be considered. Throughout the whole process, dry ice is needed in order to transport the vials. Dry ice poses yet another obstacle since it's production has been lowered since it relies on other chemicals that have been used less since the pandemic started. In some places there are shortages of the product. The handling of dry ice can also be dangerous. A vaccine seemed like all good news, but new transportation roadblocks pose yet even more problems.
