I had the privledge to read "The Vaccine Book" by Dr. Bob Sears prior to it going on sale to the general public and it was, by far, the most informative book that I have read on the subject of vaccines. When I first started reading it, I assumed it would be another boring book by a doctor. It was exactly the opposite!! It answered all of the questions that I had, in addition to educating me in areas that I didn't even think about. He puts it all in a context that is very easy to read and understand. I would highly recommend this book to anyone that has children.
