COVID-19 Aşıları İlk Yılda Dünya Çapında 20 Milyon Ölümü Kurtardı

Yayınlanan yeni bir modelleme çalışmasına göre, Lancet Enfeksiyon HastalıklarıCOVID-19 aşılarının, aşı programının ilk yılında dünya çapında 20 milyon ölümü önlediği tahmin ediliyor.

  • etkisini ölçmek için ilk modelleme çalışması[{” attribute=””>COVID-19 vaccines on a global scale estimates that 19.8 million out of a potential 31.4 million deaths were prevented in the first year after vaccines were introduced (December 8, 2020 – December 8, 2021).
  • A further 599,300 deaths could have been averted if the World Health Organisation’s target of vaccinating 40% of the population in every country by the end of 2021 had been met.
  • High- and upper-middle-income countries accounted for the greatest number of prevented deaths (12.2 million/ 19.8 million), highlighting inequalities in access to vaccines around the world.
  • The study is based on data from 185 countries and territories and is the first to assess deaths averted directly and indirectly as a result of COVID-19 vaccination, using COVID-19 death records and total excess deaths from each country (or estimates where official data was not available). 

COVID-19 vaccines reduced the potential global death toll during the pandemic by more than half in the year following their implementation, according to estimates from a mathematical modeling study published on June 23, 2022, in World Health Organisation’s target of vaccinating 40% of the population in each country with two or more doses by the end of 2021 had been met.

The study was carried out by researchers at the Medical Research Council Centre for Global Infectious Disease Analysis at Imperial College London, UK. It was funded by a Schmidt Science Fellowship in partnership with the Rhodes Trust, World Health Organisation, UK Medical Research Council, Gavi, Bill and Melinda Gates Foundation, National Institute for Health Research and Community Jameel.
