Delaying people’s second COVID-19 vaccine dose likely prevented tens of thousands of hospitalisations and thousands of deaths in England, finds a retrospective analysis from researchers at the Jameel Institute at Imperial and the MRC Centre for Global Infectious Disease Analysis. The study attempted to quantify the impact of delaying the delivery of second vaccine doses on the epidemic in England, the findings of which are published in The Lancet Public Health.
