The operation of Covid-19 vaccination centers in the Czech Republic costs tens of thousands of crowns a day, most of the sum being spent on the staff, and some hospitals addressed by ČTK have enumerated their overall vaccination spending since its start in late 2020 at millions of crowns. The operation of the national vaccination center in Prague's O2 universum arena, which jabs about 6,600 to 6,700 people a day at present, cost some CZK 1.8 million in May, its first month in operation, the supervising Central Military Hospital (ÚVN) said. ÚVN pays for the services the O2 universum provides for the vaccination center's operation, such as cleaning, security, accreditation services, information system, heating, air-conditioning, water and energy consumption. The rent the ÚVN has to pay to Bestsport is a symbolic CZK 1,000 crowns for the whole rent period.
