“The original concept of herd immunity is that when a population experiences the natural disease, and in childhood diseases it meant the childhood population experienced certain childhood diseases, natural immunity would be achieved. A robust, qualitatively superior, natural ‘herd immunity’ within the population that would then protect other people from getting the disease in other age groups.
… I’ll just take influenza, for example. When you have enough circulating influenza of a certain strain in a population, the population achieves at some point a ‘herd immunity’ effect…. Because enough people have experienced it, they’re protected naturally, and then that protection confers protection on other people. But the vaccinologists have adopted this idea of vaccine-induced herd immunity. The problem with it is… is that all vaccines only confer temporary protection, at least the vaccines that we have been using, only confer temporary protection. And pertussis vaccine is one of the best examples.
Whole cell pertussis, DPT vaccine, was used since the late-1940s, universally in our country. … When you look at effectiveness of either the whole cell or this acellular pertussis vaccine, what you find is that there’s a lot of problems with extended vaccine-induced immunity. So you have a very short shelf life, basically. And what is the reason for that? Well, pertussis vaccines have been used for about 50-60 years, and the organism has started to evolve to become vaccine resistant…
… And I can read you the results of one study looking at what is the pertussis organism about now, B pertussis… ‘Results showed that the progressive gene loss occurred in finished B pertussis strains isolated during a period of 50 years and confirmed that B pertussis is dynamic and continuously evolving, suggesting that the bacterium may use gene loss as one strategy to adapt to highly immunized populations.’
… Because you know what, every life form… wants to live. Wants to survive. Universal principle. And viruses and bacteria are no exception. And when you put a pressure on a virus or bacteria that’s circulating, with the use of a vaccine that contains a lab-altered form of that virus or bacteria, it doesn’t seem that it would be illogical to understand that that organism is going to fight to survive, it’s going to find a way to adapt in order to survive. And I think that this is not something that’s really understood generally by the public—that vaccines do not confer the same type of immunity that natural exposure to the disease does.”
