This is a MUST READ for biology teachers. I had only heard snippets of this story, and they seem to have been related to me incorrectly. I am so glad I have read (listened) to this book. Jacobs does a great job with his early life, and that of his parents. She addresses the controversy of the killed vs. weakened vaccine, Salk vs. Sabin, and other stories. Jacobs gives us real insight as to the founding of the NFIP (National Foundation for Infantile Paralysis) which started the March of Dimes. The beginning of this is amazing, and gave rise to Salk's idea that the people of the nation own the vaccine, as they provided the funds for its development. Again, I say, READ THIS BOOK. It is really long, but all really good books are!
