Mock drill simulates Colorado's arrival of first Covid-19 vaccines.

VAIL, COLORADO - NOVEMBER 8: Vail Health Hospital pharmacy technician Rob Brown works on practicing the procedure of reconstituting mock Covid-19 vaccines in the sterile compounding room in the pharmacy on December 8, 2020 in Vail, Colorado. From one vial, once reconstituted to be administered to a patient, there are five doses of the vaccine. With the state expecting its first shipment of a COVID-19 vaccine in a matter of days, the state health department ran an exercise to see how ready it is to take on such a mass vaccination campaign. The Pfizer vaccine, which is the first shot expected to gain federal approval, will be difficult for the state to distribute as it needs to be stored at sub-zero temperatures and requires two shots. The Colorado Division of Homeland Security and Emergency Management held a dry run or drill of receiving the vaccines in a thermal shipping container at Denver International Airport, using a courier car to take the vaccines to Vail Health Hospital and then the path the vaccines will follow once at the hospital from the pharmacy to a patient receiving the vaccine.
