The idea behind the second dose being delayed in the UK was it was better to give 24 million and 80% coverage to the most vulnerable people with 1 dose over 12 weeks (assuming 2 million per week), then to give 2 doses to 9 million and 1 dose to 3 million over 12 weeks .8 * 24 = 19.2m covered in scenario 1 .959 + .83 = 10.95m covered in scenario 2 Even if it were 60% with 1 dose and 95% with 2 it would be .6 * 24 = 14.4m covered in scenario 1 .959 + .83 = 10.35m covered in scenario 2
