To do so requires Pfizer, their shipping partners, and the administration facilities to use dry ice to maintain the very low temperatures. Dry ice is the solid form of carbon dioxide and it sublimates at -78F. The sublimation of the dry ice turns the solid into a gas that can be hazardous to humans in elevated concentrations.   Read the full article here.
