How many lives may have been saved because of vaccination?

The World Health Organization has taken note of a report by the medical journal The Lancet, which estimates that millions of lives have been saved by vaccination against Covid-19.

Countries around the world have the vaccine of its citizens has intensified since the outbreak of the virus more than two years ago.

SA has administered more than 36.8 million vaccines to date.

Researchers from the Imperial College London looked at deaths per country over the course of a year from when vaccines were introduced in early 2020. They also looked at the analysis of expected excess deaths to account for underreporting of deaths. The data looked at 185 countries and territories.

They then compared the two analyzes as if no vaccines had been delivered.

The model estimated that over 18 million deaths did would have occurred without vaccination and around 14 million deaths were prevented by the vaccine.

“Based on our model fitting officially reported Covid-19 deaths, we have estimated that 18.1 million (95% credibility interval [CrI] 17.4–19.7) deaths from Covid-19 would have occurred worldwide in the first year of the Covid-19 immunization program without vaccination.

“Of these, we estimated that vaccination prevented 14.4 million (95% CrI 13.7-15.9) deaths due to Covid-19, which corresponds to a global reduction of 79% in deaths (14.4 = millions out of 18.1 million) in the first year of Covid-19 vaccination. These vaccine impact estimates do not take into account the potential underestimation of Covid-19-related deaths.”

Last week, WHO Director-General Tedros Adhanom Ghebreyesus said: “More than 60 % of the world’s population have now completed a primary vaccination course against Covid-19.”

He said on Wednesday that more than 12 billion vaccines have been distributed around the world in the last 18 months , with 75% of global health workers and the over-60s now vaccinated.

< p>“On the other hand, hundreds of millions of people, including tens of millions of health workers and the elderly in low-income countries, remain unvaccinated, what means they are more vulnerable to future waves of the virus,” he added.
