Sticking sharp needles into small children doesn't sound like a nice thing to do. But vaccination is definitely a case of being cruel to be kind. This new title in the You Wouldn't Want to Live Without series relates the fascinating history of vaccination, and describes in simple terms how and why vaccination works. This simple technique has saved millions from deadly diseases--and in future, with new methods of delivery, we might even be able to do without that needle.

This book combines facts and humorous cartoons to describe how vaccines were developed and how many lives were claimed by diphtheria and polio before vaccines were available.
