Herd Immunity. Even non-science types have a vague idea of what it means. Most of us realize it refers to the protection from viral infections when a large percentage of the population obtains immunity to it. A large immune population helps prevent the spread of the virus. But how is that immunity achieved?
According to the World Health Organization (WHO), the methods to obtain herd immunity used to be found on this web page. The page, titled Coronavirus Disease (Covid-19): Serology and dated 9 June, 2020, can be found on the Web Archive (Wayback Machine): https://web.archive.org/web/20201101161006/https://www.who.int/news-room/q-a-detail/coronavirus-disease-covid-19-serology
According to the WHO, on June 9, 2020, herd immunity was defined as
“the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection.” (all emphasis mine)
An accurate and accepted definition, one that concurs with almost every other explanation on the internet and in every basic biology book I’ve ever seen.
Now compare this with the explanation currently on the same page as of 13 November, 2020. (https://www.who.int/news-room/q-a-detail/coronavirus-disease-covid-19-serology)
Now, the WHO states that 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.”
What happened to that other part? You know, the part about herd immunity being developed through previous infection?
Furthermore, they state that:
“Herd immunity is achieved by protecting people from a virus, not by exposing them to it.”
Again, where’s the acknowledgement that herd immunity can be, and has been, established through previous infection?
The WHO not only chooses to ignore one of the main methods of achieving herd immunity, it also asserts some deceitful claims, if not flat out lies. For example:
Vaccines train our immune systems to develop antibodies, just as might happen when we are exposed to a disease but — crucially — vaccines work without making us sick.
Really? If you don’t personally know someone who has gotten sick from a vaccine, or have seen the headlines of negative reactions from the experimental Covid-19 vaccine, check out all the possible negative side effects listed in the inserts of all vaccines: https://immunize.org/vaccines/
Vaccinated people are protected from getting the disease in question.
This is not always true. The makers of the experimental Covid-19 vaccines have stated it is unknown if the vaccine prevents transmission of the virus. Also, vaccinated people CAN get sick regardless of vaccination with any vaccine. (e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2640897/)
Why would the WHO change the definition of herd immunity to completely ignore the other major half of it? Well, other than pushing the narrative that the experimental Covid-19 vaccine is the only way to save humankind from the Corona virus. Which, of course, raises an entirely new set of additional questions.
