A total of 33.51 million people in Britain have received the first dose of a COVID-19 vaccine, with more than 12 million people having been given both doses, according to official figures released on Saturday.
Officials also reported a further 2,061 coronavirus cases and 32 deaths within 28 days of a positive test.
COVID-19 infections in adults of all ages fell by 65% after a first dose of AstraZeneca or Pfizer vaccine in UK research, which scientists said showed the real-world impact of the nation’s immunisation campaign against the pandemic.
Crucially, the research was conducted at a time when a new and more infectious variant of the coronavirus, called B1.1.7, was dominant in Britain, but still found vaccination was just as effective in elderly people and those with underlying health conditions as it was in the young and healthy.
