30 December 2020 • 12:01am Patients wait to be vaccinated at The Hive, home of Barnet Football Club, in Cannons Park, north London Credit: kirsty o'connor/pa SIR – I was furious when I read the letter (December 28) from Dr Claire Barker, who attempted to volunteer as a Covid-19 vaccinator but was unable to supply the 21 documents demanded during the registration process. I was further dismayed by your report yesterday that Nightingale hospitals are empty because, according to Saffron Cordery, the deputy chief executive of NHS Providers, “we can’t conjure staff out of thin air”. It seems that, in the battle against Covid-19, we are witnessing the triumph of bureaucracy over desperately needed creativity.
