"Vaccinations have saved millions, maybe billions, of lives, says Michael Kinch, associate vice chancellor and director of the Center for Research Innovation in Business at Washington University in St. Louis. Those routine shots every child is expected to get can fill parents with hope that they're protecting their children from serious diseases."

"But vaccines also inspire fear that something could go terribly wrong. That's why Kinch's new book is aptly named: Between Hope and Fear: A History of Vaccines and Human Immunity."
