The use of references in the book are excellent, and I especially appreciate the references mentioned throughout the book after many important points. I also think Dr.O'Shea did an excellent job of placing certain terms or important points in bold. The discussions on the difference between Vaccination vs. Immunization, Natural vs. Artificial Immunity, and the decline in diseases prior to vaccines also make very good and important points. If anyone has any doubts as to whether or not the government is putting their health and well-being first, just read this book and you will find the answer when he explains the money and political sides of vaccination. And remember, VACCINATION is the correct term, NOT IMMUNIZATION.
