What is one of the main focuses of immunology?

The study of immunology primarily revolves around understanding and developing immunity. Immunology seeks to uncover how the immune system functions, how it protects the body against pathogens like bacteria and viruses, and how it can be harnessed to enhance immune responses. This field also explores the mechanisms of both natural and acquired immunity, the role of vaccines, and the responses of the immune system to various challenges.

While other areas, such as studying body temperature and examining blood types, are important in medical science, they do not primarily focus on the immune system’s response to disease and the development of immunity. Understanding diseases is certainly a critical aspect of medicine, but immunology specifically hones in on how immune responses can mitigate those diseases, placing greater emphasis on the body's defenses rather than the diseases themselves. Thus, understanding the mechanisms of immunity and the development of new methods to protect against diseases through immunological principles is central to this field.
