In December 2019 a new virus emerged, one that caused a global pandemic. Millions were infected. In the recesses of their fragile bodies a battle raged: between the immune system and the virus. But what is the immune system? What are its components? How do they work?

One way to understand this system, arguably the most complicated in human physiology, is by walking in the footsteps of history, one observation and experiment at a time – beginning with the first written record of the concept of immunity in 430 BCE and travelling through the ensuing centuries, which gave the world vaccines, organ transplantation, novel therapies for cancer and now the understanding and tools to tackle the pandemic virus.

An entertaining and accessible work of popular science, At the Edge of Mysteries introduces the reader to a compelling cast of characters, from Edward Jenner and Louis Pasteur to the Nobel laureates of the modern day. This book glimpses into their lives and times – seeking clues to their genius and celebrating their yearning for discovery – and asks the question of what can be learned from the past in the age of global pandemics.
