Boris Johnson raised eyebrows on Tuesday when he suggested that the reduction in Covid infections, hospital admissions and deaths had not been achieved by the vaccination programme, with the lockdown doing "the bulk of the work". Thankfully, less than 24 hours later, science had proved the Prime Minister wrong. New research from NHS England and the University of Manchester showed the stark difference in cases, admissions and deaths for elderly people who had been vaccinated compared to those who had not. In a large study involving more than 170,000 people, researchers had scrupulously case-matched participants to make sure the results were not skewed by underlying conditions, sex or geographical location. The results show that far from having little impact, the rate of Covid-related hospital admissions fell by 75 per cent in vaccinated 80 to 83-year-olds within 35 to 41 days of their first dose of the Pfizer jab. The rate of people getting Covid dropped by 70 per cent, with the number of positive tests falling from 15.3 per 100,000 people to 4.6. The authors conclude: "The nationwide vaccination of older adults in England with the [Pfizer] vaccine reduced the burden of Covid-19."
