The World Health Organization has changed the definition of “herd immunity” on the Covid section of their website, inserting the claim that it is a “concept used in vaccination”, and requires a vaccine to be achieved.
Both of these statements are total falsehoods, which is demonstrated by the WHO’s own website back in June, and every dictionary definition of “herd immunity” you can find.
To quote the WHO’s own original definition:
Herd immunity is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or a natural immunity developed through previous infection.
This definition was posted on the WHO’s website on June 9th of this year, and conforms with the general usage of the term for generations.
Then, on October 15th, we woke up to find the words on the side of the barn had changed. The definition has been altered to this:
‘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.
No explanation is offered for the change, in fact note of the change is made on the website at all.
Indeed all the previous versions of the website have been totally wiped from the wayback machine. A telling thing to do, in and of itself.
