My thoughts on this short but sweet little book are mixed. On the one hand, this is an excellent starting place for vaccine skeptics and those questioning the bloat of the medical-industrial complex. On the other hand, Dr Cowan leaves a lot up to speculation, and some of his points lack data. There is a sort of earthy pseudo-spiritualism to the whole thing that begs to be grounded in something substantial like Christianity but it just isn't.
The crux of Cowan's theory around the interaction between vaccines and autoimmunity revolves around a niche understanding of the cell that opposes the mainstream cellular theory. This theory states that cells achieve a fourth state of water known as gel, and that toxic components of vaccines interrupt this state. Cowan goes so far as to state that most diseases are simplifiable to a dysfunction in the water regulation of cells, and though this would be appealing and simple, it isn't supported by much evidence. This doesn't represent the whole of his theory, but at least a whole chapter is dedicated to it.
Many of his issues with vaccines and healthcare systems in modernity seem to be philosophical, such as his understanding of human development in "[having] four distinct yet interpenetrating 'bodies' of disease". What a strange way of viewing childhood illness and it's contribution to the immune system over the life span. This strange phrasing and theory is supporting by compelling claims, such as contracting measles treats and prevents nephrotic syndrome, as opposed to the measles vaccine, which neither treats nor prevents this syndrome.
Many arguments were excellent. I enjoy how Cowan drags the conflicts of interest between the government officials and their participation in pharmaceutical companies into the light. I love his exposure of the conflicts in the claims that vaccines have "cured" illnesses that were basically on their way out through improvements in nutrition and waste management. I really enjoyed his breakdown towards the end of the book that names nearly every childhood vaccine, their ingredients, and how toxic they are. And I loved his dietary advice for those suffering from autoimmune diseases, which I would agree are largely caused by poor diet, lack of exercise, and unnecessary vaccinations.
High point: when he demonstrated that someone who gets chicken pox as a kid and is exposed to their own kids getting chicken pox is almost a non-candidate for late-life shingles as the immune system is re-exposed and armed for the reemergence of the virus. However, someone who is vaccinated may contract shingles from the vaccine, and they are not exposed to the virus in their kids who are vaccinated, which increases the likelihood of contracting shingles even in adults who had chickenpox as kids.
Low points: many of Cowan's claims are only supported by one unilateral piece of evidence. I understand that it is hard to gather evidence on these subjects due to the aforementioned conflicts of interests and profit incentives that keep people from investigating, but it still makes it hard for someone to jump in with both feet on this presentation alone. Another low point was his use of "she" and "her" to refer to hypothetical patients in scenarios for demonstrations. Not only does this fly in the face of the last entire history of the English language, but this type of virtue-signaling actually achieved the opposite effect. Most of the time this "she" is on the receiving end of some kind of autoimmune illness, so it comes across opposite from the intended outcome (giving more representation to women) and appears more that women are merely the main possessors of bad health.
