The unprecedented rapidity of development and rollout of COVID-19 vaccines is hailed as “an extraordinary global health feat”.
A study published in The Lancet Infectious Diseases modelled the spread of the disease in 185 countries and territories between December 2020 and December 2021. It found that without COVID vaccines, 31.4 million people would have died, and that with the vaccines, 19.8 million of these deaths were avoided.
Many more deaths could have been prevented if access to vaccines had been more equal worldwide. Nearly 600,000 additional deaths – one in five of the COVID deaths in low-income countries – could have been prevented if the World Health Organization’s global goal of vaccinating 40 per cent of each country’s population by the end of 2021 had been met, the research found.
The researchers, from the Imperial College London, said: “The inequitable distribution of vaccines prolonged the pandemic, and exacerbated the probability and frequency of the emergence of variants of concern.”
“Provision of vaccine doses from high-income to lower-income countries is therefore not only moral but also pragmatic,” they said.
“The saving of more than 19 million lives by the unprecedented rapidity of development and rollout of COVID-19 vaccines is an extraordinary global health feat.”
The study highlighted lessons to be learned from the pandemic: improvements in vaccine supply, cold-chain operations, and public confidence.
