The evidence for this is overwhelming and is discussed in greater detail in many of our articles on the subject listed at the end of this article.
This is absolutely not to say that there are not loving, upstanding people who are doctors, researchers, or otherwise as part of the Western medical establishment. Not at all. I believe most of them are. However, when it comes specifically to the family doctors and pediatricians who are trusted by their patients to make recommendations for their patients' health and well-being, there is a limit to how far they can push the boundaries of the highly controlled business structure they find themselves in.
This is probably most obvious when it comes to vaccines. I don't think any doctor could tell me straight-faced that if they decided that vaccines were not safe for their patients, and they were openly vocal about it in public, that there wouldn't be pushback from their industry, including intimidation and threats of losing their medical license. And so, unfortunately, there is a built-in bias from the start, and doctors know that going down the path of truly doing their own independent research into the safety and effectiveness of vaccines, in order to make an informed decision about what they will recommend to their patients, will either be a lot of work for nothing or will end up with them having to fight against their powerful establishment and risk losing their livelihood.
