Resumen del Libro

Behind the appearance of an innovative vaccine there is a history of determination and struggle, of breaking established models, and of overcoming the mistrust that generates a new theory. In this book we are going to learn about those stories, the stories of great scientists who fought to prove new theories and are now behind vaccines that save or will save millions of lives. We will experience with them the moment when they discovered that they had defeated a virus. We will travel inside the infectious agents to learn about their ability to gain ground in humans, the biological tools they use to evolve, the enormous threat they pose permanently lurking in nature, where it is estimated that there are more than 700,000 viruses with the capacity to create diseases in humans.
