Clinical and cellular immunology is a field of medical science that explores the complexities of the immune system in health and disease. It involves the study of immune responses at both the clinical and cellular levels. Researchers and practitioners in this field investigate how the immune system functions, how it defends against pathogens, and its role in various diseases, including autoimmune disorders and immunodeficiency. By understanding the cellular interactions and molecular processes involved in immune responses, clinical and cellular immunology contributes to the development of treatments, vaccines, and therapies aimed at modulating immune function and addressing immunological disorders
