People aged 70 and over and those listed as clinically extremely vulnerable in England have begun to receive the first dose of coronavirus vaccine from Monday. Nadhim Zahawi, the minister responsible for the vaccine rollout, said despite "lumpy" vaccine supply, he was "confident" that Britain is able to vaccinate all 15 million people in the top four priority groups by mid-February.
