Rollout of the Pfizer BioNTech and Oxford AstraZeneca vaccines has led to a substantial fall in severe covid-19 cases requiring hospital admission in Scotland, suggest the results of the first study to report on the impact of the UK’s vaccination strategy.1 - The results, available as a preprint, showed that four weeks after the first doses of the Pfizer BioNTech and Oxford AstraZeneca vaccines were administered the risk of hospitalisation from covid-19 fell by up to 85% (95% confidence interval 76 to 91) and 94% (95% CI 73 to 99), respectively.
