Understanding Immunology is a well-established introduction to this complex subject for readers with no previous exposure. It is aimed primarily at undergraduates in biological sciences, biomedical sciences and medicine. The selection and order of topic coverage is designed to instruct effectively, and a variety of boxed examples add depth and historical context for those readers wanting to go beyond the essentials.
