Coronavirus: The thing we are getting WRONG about herd immunity
The World Health Organisation (WHO) warned against allowing unethical spread of the coronavirus in the hope to achieve herd immunity. WHO chief Tedros Adhanom Ghebreyesus said, “Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic.”
WHO director-general said at a press briefing on Monday that health officials typically aim to achieve herd immunity – where the entire population is protected from a virus when the majority are immune – by vaccination. Tedros noted that to obtain herd immunity from measles, for example, about 95% of the population must be vaccinated, AP reported.
