WHO Chief

World Health Organization head Dr Tedros Ghebreyesus has stated that herd immunity approach is “ethically and scientifically problematic.” The approach calls for spreading of the virus to achieve herd immunity. Dr Ghebreyesus said that the approach has never been followed as a strategy in history and it would cause “unnecessary suffering”. “Herd immunity is achieved by protecting people from a virus, not by exposing them to it,” he said.
