This book provides a great history of vaccine from its inception. You'll not find this book impartial, but I would call it informative. Unlike many books about vaccination, I appreciated that this author cites references throughout each chapter!!! IT was a pleasure to be able to look up the information that he used in his book.
The book is not made to be a reference book, but instead tells the story of vaccination. Everything from its dirty history to how the minds of those who practiced medicine have changed.
I couldn't say it any better than to say that this book was fun.
