Wall Street Journalさんのインスタグラム写真 - (Wall Street JournalInstagram)「When the British government provisionally authorized use of a Covid-19 vaccine last week, it set in motion a logistical test that will define the next stage of how the world tackles the coronavirus pandemic: the delivery of the vaccines.⠀ ⠀ The shots that British citizens began receiving on Tuesday had been sitting only days earlier in ultracold freezers across the English Channel at the Pfizer plant in Puurs, Belgium. Vials of the vaccine were stored at nearly 100 degrees below zero Fahrenheit and put into custom-made thermally protected shipping containers packed with dry ice before being loaded onto anonymous trucks for delivery.⠀ ⠀ At a sports center in Cardiff, Wales, on Tuesday, defrosted vaccines—which had arrived just the day before—were being removed from cold storage and prepared for injection. Patients sat waiting in chairs positioned safely apart, and each was escorted by a nurse to a booth to receive their initial dose. Appointments were set at 15-minute intervals, despite nurses needing just two minutes to confirm personal details and administer the shot. ⠀ ⠀ For vaccines to halt then reverse the pandemic, similar drills must occur thousands of times over, all around the world, in places far less organized than Northern Europe. Countries and logistics companies are scrambling to prepare for the unprecedented challenge of shipping millions—eventually billions—of doses at carefully controlled temperatures.⠀ ⠀ Even as countries including the U.S. authorize vaccines and begin inoculations, the U.K. will emerge as a laboratory for what is possible at high speed and what might go wrong.⠀ ⠀ Read more at the link in our bio.⠀ ⠀ 📷: @garethphillips_ for @wsjphotos」12月11日 4時10分
