Immunology is the study of the immune system and how it works to prevent infection in the body. With the ability to mount a response against virtually any foreign material and return to a quiescent state following neutralization of the threat, this fascinating organ system displays remarkable specificity and plasticity.

The immune system offers protection from infection through various lines of defence. It is a crucial mechanism for protecting us from bacterial, viral and parasitic infections. Diseases such as autoimmune disorders, allergies and cancer can occur as a result of the immune system not functioning as it should.
