What is the primary purpose of immunology?

The primary purpose of immunology is to research vaccines and immunity. This field focuses on understanding how the immune system functions, how it responds to pathogens, and how vaccination can enhance immunity against diseases. Immunologists study the various components of the immune system, including antibodies, T cells, and B cells, to understand how they identify and eliminate infectious agents.

This knowledge is crucial in developing effective vaccines that train the immune system to recognize and combat harmful pathogens before they can cause illness. By researching vaccines and immunity, immunology plays a vital role in public health and disease prevention, addressing both existing and emerging infectious diseases.
