Immunology, as such, is that part of the biomedical science which concerns itself generally with the anatomy and physiology of the immune system. Its concern is how a body can defend its system against such pathogens, including viruses, bacteria, and fungi; more specifically, it aims at the differentiation between dangerous invaders and the cells of the body. The main themes of research in immunology are mechanisms of immune responses, roles of the different classes of immune cells, especially T-cells and B-cells and design of vaccines and immunotherapies.

Aggressive knowledge in immunology is required for the cure and treatment of many diseases, for example, autoimmune diseases, allergies, even cancer. Researchers constantly develop newer vaccines and therapies that can possibly improve the fight of the immune system against infections and diseases.

This covers investigation of the phenomenon of immunological memory whereby the immune system can respond more quickly to pathogens it had previously encountered. This forms the basis for the principle of design that underlies vaccines intended to confer long-term immunity against certain diseases. Immunologists will carry into some genetic, molecular biology, and biochemical information that will identify all the necessary questions associated with regulation of the immune system and to what extent is it dysregulated. Targeted therapies and personalized medicine, for example will require inclusion.
