However, it was marred by decisions that saw those most in need of a vaccine in some countries wait too long, while those perceived to be least at risk getting them first. Now, Prof Carlos Alós-Ferrer of the University of Zurich writes about how he and his colleagues’ latest research in Frontiers in Public Health shows that one maths procedure can ensure a fair distribution of scarce vaccines across the globe. Remember when Covid-19 vaccines first became available? After many months of lockdowns and increasing casualty rates, people across the planet were allowed to exhale a collective sigh of relief. However, as is always the case when new vaccines are developed, there were not enough doses for all who wanted them. Rationing had to be imposed. Unfortunately, the rationing procedures violated elementary ethical principles, which might have led to some elderly and at-risk patients being neglected while younger, healthier citizens were already vaccinated. How did it go wrong? Vaccine acquisition and allocation across the world was as centralized […]
