Trying to reach herd immunity is unethical and unprecedented, WHO head says
“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 Tedros Adhanom Ghebreyesus said at a Monday media briefing. “It is scientifically and ethically problematic.”
In a public health context, herd immunity typically describes a scenario in which a large enough share of the population is vaccinated against a disease to prevent it from spreading widely, thereby providing default protection to a minority of people who have not been vaccinated.
But as there is still no vaccine for the coronavirus, achieving herd immunity in the current environment would require a large number of people to contract the virus, survive covid-19, and then produce sufficient antibodies to provide long-term protection.
While the scientific community has roundly rejected herd immunity the approach, public interest in it has waxed and waned amid pressure to reopen schools and economies.
Last month, President Trump appeared to praise the idea during a town hall in Pennsylvania.
