MOSCOW (Sputnik) – The World Health Organization (WHO) estimates that less than 10 percent of the global population have antibodies to the coronavirus, WHO Chief Scientist Soumya Swaminathan said.
The only way to achieve mass herd immunity is through vaccination, the WHO chief scientist stressed.
According to Swaminathan, the currently approved vaccines offer good protection against severe disease, hospitalization and death from COVID-19. The vaccines’ effectiveness with regard to mild disease and asymptomatic coronavirus infection is still being studied.
More than 114 million coronavirus cases have been confirmed globally since the start of the pandemic last spring. According to Johns Hopkins University data, the global COVID-19 death toll stands at over 2.5 million.
