A study published by Imperial College London (IC) in the Infectious Diseases section of The Lancet magazine showed that the new coronavirus vaccine prevented nearly 20 million deaths in the first year after it was first vaccinated around the world. There are 12.2 million people in upper-middle-income countries.
When doing relevant data modeling, researchers used official estimated data from 185 countries. Data show that vaccines have prevented 4.2 million, 1.9 million, 1 million, 631,000 and 507,000 new deaths in India, the United States, France and the United Kingdom respectively.
The WHO stated in a statement released on May 5 that the latest estimates show that from January 1, 2020 to December 31, 2021, the global number of deaths directly or indirectly related to the new crown epidemic was approximately 14.91 million. people (actual range is between 13.3 million and 16.6 million).
On December 8, 2020, a retired shop assistant in the United Kingdom received the world’s first shot of the COVID-19 vaccine, and then started a global vaccination campaign.
In the one year after the first dose of the COVID-19 vaccine (December 8, 2020 to December 8, 2021), more than 4.3 billion people around the world were vaccinated.
However, this article also pointed out that if each country achieved the 40% vaccination target set by the WHO before the end of 2021, more deaths could have been avoided.
