The World Health Organization said Monday that the idea of “herd immunity” to stop the spread of the novel coronavirus is an “unethical” practice.
- “Herd immunity is achieved by protecting people from a virus, not by exposing them to it,” Tedros Adhanom Ghebreyesus said during a virtual press briefing.
- He said “herd immunity is a concept used for vaccination, in which a population can be protected from a certain virus if a threshold of vaccination is reached.”
The WHO leader pointed to measles. About 95% of people are vaccinated for measles so the leftover 5% would be protected from the virus, according to CBS News.
- “Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic.”
For the novel coronavirus, 70% to 90% of Americans would need to have coronavirus antibodies for herd immunity to be achieved, according to CBS News.
Right now, less than 10% of the entire world has immunity to the novel coronavirus, which leaves much of the world still susceptible, NBC News reports.
