When I stumbled across this book on the Internet, I thought it might be a worthwhile read. I had no idea what a pleasure reading it would be. Biss, an essayist and university lecturer, examines what lies behind people’s fears of vaccinating their children. Like many of us, she concludes that vaccines are safe, effective, and almost miraculous tools for protecting children against needless suffering. But she is not out to demonize anyone who holds opposing views. This is a thoughtful and beautifully written book about a very important topic.
