How will America's largest ever immunisation campaign work?

Available for over a year

The first Covid-19 vaccination in the United States has taken place, as the country gears up for its largest ever immunisation campaign. An intensive care nurse in Long Island, New York is believed to have been the first person to be given the jab. Millions of vials of the Pfizer/BioNTech vaccine are being distributed, with 150 hospitals expected to receive doses on Monday. The US vaccination programme aims to reach 100m people by April. Its chief scientific adviser is Dr Moncef Slaoui. Photo shows: Sandra Lindsay(L), a nurse at Long Island Jewish Medical Center, is given the Covid-19 vaccine Credit: Getty Images
