Levels antibodies against COVID-19 internationally is likely higher than previously thought as up to two-thirds of the world’s population could now have such antibodies against the coronavirus, either after vaccination them or after infection with the virus.

Its researchers World Health Organization (WHO) and the serosurveillance platform SeroTracker, which published in the medical journal PLoS Medicine, calculated that the presence of coronavirus antibodies increased from 7.7% in June 2020 to 59.2% in September 2021, and today it has increased even more more, perhaps up to two-thirds of humanity.

The calculation is not easy, as a large percentage of Covid-19 infections are asymptomatic. Therefore, it is difficult to accurately estimate the true proportion of infections in the global population. However, the researchers’ overall estimate is that more people around the world have antibodies in their bodies due to vaccines or diseases than previously thought.
