Our bodies are equipped with "immunity," a mechanism that protects us from infection and disease. This book covers the basic mechanism of immune response, as well as infectious diseases, autoimmune diseases, allergies, and transplantation medicine, which is of current interest. The book introduces the difficult-to-understand mechanisms of immunity in an easy-to-understand manner using cartoons and text explanations, making it a worthwhile introductory text.
