Covid-19 vaccines prevented nearly 20 million deaths in a year, study estimates
Covid-19 vaccines cut the potential global death toll by more than half in the first year they were available, according to a study published Thursday in The Lancet Infectious Diseases.
The study modeled the spread of the disease in 185 territories and countries and found that without Covid vaccines, 31.4 million people would have died of the disease between December 2020 and 2021. While the pandemic has taken a devastating toll around the globe, with more than 3.5 million deaths since the first vaccine was administered in December 2020, the study estimated that vaccinations also prevented 19.8 million deaths.
