Across the country, dry-ice makers are planning to boost production of the frigid storage material needed to ship hundreds of millions of doses to hospitals, pharmacies and physicians’ offices.⠀ ⠀ Few pharmaceutical products have required such low temperatures for storage and transit. Pfizer’s vaccine, which is expected to be cleared by U.S. regulators, must be shipped and stored at minus 70 degrees Celsius to remain stable and effective. The temperature of dry ice is around minus 78 degrees Celsius. Once thawed, Pfizer’s vaccine can be refrigerated for up to five days.⠀ ⠀ Cee Kay Supply—which makes dry ice at three Missouri plants, including the one p[pictured here in St. Louis—has fielded calls from public-health departments, medical-supply and logistics companies planning to take part in Pfizer’s vaccination campaign. In November, the company bought a machine to boost the volume of dry-ice pellets it can make. It has added insulated tanks to store more carbon dioxide and more than 100 industrial coolers capable of transporting roughly $30,000 worth of dry ice.⠀ ⠀ Read more at the link in our bio.⠀ ⠀ 📷: @whitneycphoto for @wsjphotos」12月8日 0時21分
