This is my first book review and I am quite surprised at how disappointed others were with this book. I've read many books on this subject in the past 20 years, including works by Michael Collins, Peter Kuznick (Who's Afraid of Red Riding Hood?) and even Andrew Wakefield. A lot has changed with respect to vaccines and our vaccination status today.

Bad review
