Have an impact on the development of new or improved medicines and the treatment of disease. Immunology is the study of how the body defends itself against disease, includes not only defence against bacteria, parasites or viruses, but also the elimination of cancer and processes such as inflammation and wound healing. It also helps us understand how the immune system is misdirected into attacking the body’s own tissue, leading to diseases like rheumatoid arthritis, diabetes, or allergy. Pharmacology studies how drugs and other chemicals affect the functions of the body and underpins the development of new or improved medicines and the treatment of disease. You take introductory classes in biochemistry, immunology, microbiology and pharmacology in Years 1 & 2 and whichever biomolecular science degree you apply for, you can defer your final choice of degree until the end of Year 2.
