Immunologists investigate the functions of the immune system and apply this knowledge to diagnose and monitor a range of diseases and disorders.
They are concerned with understanding the development and effects of abnormal immune responses, which are associated with conditions including autoimmune diseases, allergies, immunodeficiencies and transplant rejection.
Immunologists work within clinical and academic settings, as well as in industrial research. Their role often involves identifying, characterising and measuring aspects of the immune system, including cells, antibodies and other proteins.
They develop new therapies, treatments and vaccines, with an aim to improve treatment methods for different conditions.
