Regardless of where you are on the spectrum of vaccine use in the United States, education is what we are about at Breath of Life. Dr. Sears has written a book that is aptly named,  The Vaccine Book. You can find more information about it on: http://www.askdrsears.com/topics/health-concerns/vaccines/inside-vaccine-book as well as from the NVIC (national vaccine information center): If you vaccinate, ask 8 questions: http://www.nvic.org/Ask-Eight-Questions.aspx.
