CARDIFF, WALES - DECEMBER 08: A close-up of a syringe containing a Pfizer-BioNTech Covid-19 vaccine as it is given to a patient at Cardiff and Vale Therapy Centre on December 8, 2020 in Cardiff, Wales. Wales joined the other UK nations in rolling out the covid-19 vaccine on Tuesday, a rare moment of coordination after months of disjointedness in the four nations' pandemic response. Wales introduced a 17-day "firebreak" lockdown in October and November to suppress the surge in covid-19 cases, but infections have continued to rise. (Photo by Matthew Horwood/Getty Images)
