"Vaccines are one of humankind's greatest creations in both saving lives and creating diplomacy between nations, and there is likely no one in the world who can better teach us about both than Dr. Peter Hotez. The good doctor has spent his life in the lab developing lifesaving vaccines and traveling all over the world ensuring they are put to proper use. In this deeply researched and insightful work, Peter shows us how to see the world differently and offers a guide for shaping a healthier, safer future. This book could not be more timely in a COVID—and post-COVID—world. Hotez gives us equal doses of science-driven help and human-centered hope."
