I was reading about the ultra low temperature distribution chain today. There are all sorts of problems and it's not cheap but in developed countries it exists and is routinely used. It maintains low temperature using a mixture of liquid nitrogen, dry ice and ultra refrigerators. These last are standard equipment in any biochemistry lab. LN2 and dry ice are adequately locally available just about anywhere in the developed world.
It's still not easy, as the ultra cold chain won't be easy to extend to lots of local vaccination centres. It may need people to come to a smaller number of large centres which is of course a potentially good way to spread the virus.
Away from the developed world, it won't really be usable in most places. It's hard enough maintaning any kind of cold chain, even ordinary 4C or so fridge temperatures, in remote areas.
