In a year since the vaccine was first introduced in December 2020, more than 4.3 billion people have been vaccinated, saving 20 million lives, according to research published Thursday in The Lancet Infectious Diseases magazine.
If low-income countries reach the World Health Organization’s goal of 40% vaccine coverage by the end of 2021, an additional 600,000 lives could be saved, the study says.
The findings “calculate how bad the infection would have been if we did not have these vaccines,” said Oliver Watson, a leading researcher at Imperial College London.
“Disaster will be the first word that comes to mind,” Watson said of the deaths that have occurred without widespread vaccination.
According to Ever World’s data, more than 6.3 million people have died from the corona virus, including more than one million Americans. Over 40,000 New York City residents died From the virus, health officials said.
The researchers examined data from all but ten of the world’s 195 countries, and vaccines prevented 19.8 million deaths, including 4.2 million in India and 1.9 million in the United States.
Vaccines have saved one million lives from the virus in Brazil, and more than half a million in both France and the United Kingdom, the researchers said.
The study found that 14.4 million deaths were avoided when the reported COVID-19 deaths alone were calculated, but the number of survivors increased significantly when scientists calculated the number of deaths associated with the virus.
There were some significant limitations in the study. The researchers said that China, the world’s most populous country, was one of the countries most excluded from the study due to a lack of information on the impact of the virus on its large citizens. The effect of wearing a mask, locking and possible COVID-19 mutations in the absence of the virus were not considered in the study.
The model, unpublished by the Seattle-based Institute for Health Metrics and Assessment, estimates that 16.3 million lives were saved by the vaccine.
“As scientists we disagree on the numbers, but we all agree that the Govt vaccines saved a large number of lives,” said Ali Mogdat of the Institute, adding that strict policies would have been implemented around the world had it not been for the vaccines during the Delta variation.
Adam Finn of the Bristol Medical School in the UK, who was not involved in the findings released on Thursday, said: “Even though we did well this time – we saved millions and millions of lives – we could have done better, and we should do better in the future.” .
