Great news, but I think the importance of the -80 degrees centigrade storage requirement is underestimated.

Serbia, where I live, has ordered this vaccine. And our medical system is far from world-class, but leaps and bounds from less developed countries, and I honestly think logistics here will not be able to match those requirements. I've seen tetanus vaccines just being kept in regular, commercial, refrigerators. There have been cases where they have been switched off because they were not on UPSs or not up to standards. Vehicles equipped for transport are an issue by itself.
