What is Immunology?
Immunology is the branch of biomedical science that is concerned with the study of the structure, function and disorders of the immune system. The immune system is a complex system of organs and cells that recognises foreign material, e.g. bacteria and viruses, in our bodies and builds a defence against them.
Immunology includes: the use of vaccines to protect against diseases; the role of the immune system in non-infectious diseases such as cancer and allergies and the destruction of the body’s own tissues by the immune system (autoimmunity).
A doctor who specialises in the prevention, diagnosis and management of immune system disorders is called an immunologist.
