But that’s when the alarm bells ring.
First, I am reliably informed there is no such term as ‘herd immunity’ in public health medicine. The term only exists in veterinary medicine. So this is not a medical, epidemiological or public health declaration in that case.
Then some minor character who runs the World Health Organisation:
The head of the World Health Organization has warned against deliberately allowing coronavirus to spread in the hope of achieving so-called herd immunity, saying the idea is unethical.
“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,” Tedros Adhanom Ghebreyesus said during a virtual press briefing.
For measles, for instance, it is estimated that if 95% of the population is vaccinated, the remaining 5% will also be protected from the spread of the virus. For polio the threshold is estimated at 80%.
“Herd immunity is achieved by protecting people from a virus, not by exposing them to it,” Tedros 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.”
So, herd immunity is a term used in public health medicine. It is applied to human beings, is not reserved just for animals.
No, that Snippa is agin’ it and that also the WHO chief is isn’t a defence of Snippa. For the critique isn’t over whether anyone’s agin’ it or not. It’s over the existence of the term and practice.
