World Health Organization warned against the idea that herd immunity might be a realistic strategy to stop the coronavirus pandemic, dismissing such proposals as “simply unethical.”At a media briefing on Monday, WHO Director-General Tedros Adhanom Ghebreyesus said health officials typically aim to achieve herd immunity by vaccination.
Tedros noted that to obtain herd immunity from a highly infectious disease such as measles, for example, about 95% of the population must be immunized.
Only 5% of Spain’s population has coronavirus antibodies, despite severe outbreak: study “Herd immunity is achieved by protecting people from a virus, not by exposing them to it,” he said.
