I have it, I've read it and I like it. A lot of the info in it is already on his web site
www.thedoctorwithin.com. Its an anti-vaccine book. But I'm not aware of any truly "neutral" vaccine books. An author either believes in using vaccines or doesn't. The books that people tend to say are "neutral" from what I've seen, they really aren't neutral because the authors are really "pro-vaccine" because they recommend some vaccines and/or delaying them (for example "The Vaccine Book" by Dr. Sears is pro-vaccines, and "What Your Doctor May Not Tell You About Children's Vaccinations" by Stephanie Cave, M.D. is pro-vaccines). I really like "Saying No To Vaccines" by Dr. Sherri Tenpenny, and yes of course this is an "anti-vaccine" book, but its very well-documented and she says it how it really is, its not meant to be "balanced" because all of us already know the "pro-vaccines" arguments, and this book is there to balance it out.
