Biology: Explaining the Immune System

We all rely on our immune system to keep us from getting ill. This book is about how the immune system does this. It is intended for students of biology and anyone else with an interest in the subject.
Certainly the facts about the immune system are staggering: for example,
there are as many as one hundred million different antibodies in the human immune system.
It is also certain that human health has been greatly improved through knowledge of the immune system's function: vaccination has helped reduce and in some cases, wipe out, some terrible diseases; for example, the last ever case of smallpox occurred in 1978 in Birmingham, England, the disease had been eradicated worldwide using vaccination.
This book explains how the immune system functions and how medical applications such as vaccination and antibiotic treatment, work, in a clear and concise way that is easy to understand. I hope you enjoy it and it encourages you to further widen and improve your knowledge of the function of the immune system and of biology in general.
