Health Desk- 13 Oct 2020: The head of the World Health Organization has ruled out a herd immunity response to the pandemic.
Herd immunity occurs when a large portion of a community becomes immune to a disease through vaccinations or through the mass spread of a disease.
Some have argued that coronavirus should be allowed to spread naturally in the absence of a vaccine.
But WHO chief Tedros Ghebreyesus said such an approach was ‘scientifically and ethically problematic’.
Speaking at a news conference on Monday, Dr Ghebreyesus argued that the long-term impacts of coronavirus - as well as the strength and duration any immune response - remained unknown.
‘Herd immunity is achieved by protecting people from a virus, not by exposing them to it,’ Tedros said.
