The World Health Organization has changed the definition of “herd immunity,” eradicating the pre-COVID consensus that it could be achieved by allowing the virus to spread through a population, and declaring that herd immunity solely comes from vaccines.

The change happened on the WHO’s website, in a section entitled ‘Coronavirus disease (COVID-19): Serology, antibodies and immunity’.

The original WHO definition (archived here) states that herd immunity “happens when a population is immune either through vaccination or immunity developed through previous infection. This means that even people who haven’t been infected, or in whom an infection hasn’t triggered an immune response, they are protected because people around them who are immune can act as buffers between them and an infected person.”

Summit.news reports: The original definition fails to identify the pre-COVID consensus on what is meant by “herd immunity,” which is when a population becomes protected against a virus because enough people have been infected with it to create community immunity. 

However, the WHO’s updated version is even more extreme, insisting that herd immunity can only be achieved by mass vaccination programs.

“‘Herd immunity’, also known as ‘population 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,” states the WHO website, adding, “Herd immunity is achieved by protecting people from a virus, not by exposing them to it.”

“‘Herd immunity’ exists when a high percentage of the population is vaccinated,” states the website, completely omitting the original meaning of “herd immunity,” which is when a population becomes immune to a virus by being exposed to it.

By changing the definition of “herd immunity,” the WHO is literally re-writing hundreds of years of scientific understanding as to what the term truly means in an apparent effort to silence any argument that herd immunity would have been a better approach to fighting COVID-19 than lockdowns and social distancing.
