The 2014 book Dissolving Illusions: Disease, Vaccines, & the Forgotten History follows an unusual format, as authors Suzanne Humphries and Roman Bystrianyk state up-front. They quote evidence from many historical and medical-literature sources, grouped by subject and date, and provide very little opinion, introduction, or conclusions. This allows informed readers to compare opposing statements and to draw their own conclusions. I would add that having a medical degree and working knowledge of modern physiology and immunology are almost a prerequisite as well.
