NEW DELHI: (Jul 25) COVID-19 vaccines helped prevent more than 25 lakh deaths across the world between 2020 and 2024 — for every 5,400 doses administered, one death was averted, estimates a study.

Findings published in The Journal of the American Medical Association (JAMA) Health Forum “clearly demonstrate a major overall benefit from COVID-19 vaccination during the years 2020-2024”, with 90 per cent of the life-saving benefits secured for the world’s older adults.

Researchers from the Catholic University of Milan, Italy, and US’ Stanford University analysed publicly available data on worldwide population to estimate number of people who died due to COVID-19 and whether they died before or after getting vaccinated.
