Immunologist

You study the body's defence system – the science behind vaccines, HIV, allergies, and autoimmune diseases.

What this life looks like

The immune system is the body's defence force – a remarkably complex network of cells, proteins, and signalling pathways that protects us from infection, destroys cancer cells, and maintains the boundary between self and non-self. When it works well, you are healthy. When it fails – whether because of HIV, autoimmune disease, allergy, or immune deficiency – the consequences can be devastating. As an Immunologist you study and work with this system, either as a clinical immunologist diagnosing and treating patients with immune-related conditions, or as a research immunologist investigating the fundamental biology of immunity and developing new vaccines and treatments. Africa's relationship with immunology is critical. HIV, the virus that destroys the immune system, still affects over 26 million Africans. Malaria has co-evolved with the human immune system in Africa for millennia. The COVID-19 pandemic accelerated African investment in vaccine development and immunology research. And autoimmune diseases including lupus and rheumatoid arthritis, which disproportionately affect women, are rising across the continent. Immunologists are at the centre of Africa's most important scientific and clinical challenges.

What she actually does

A Clinical Immunologist diagnoses and manages immune deficiency diseases, autoimmune conditions, allergies and hypersensitivity disorders, and the immunological complications of HIV and other infections. A Research Immunologist designs and conducts laboratory studies of immune mechanisms, develops and evaluates vaccines, and investigates the immunological basis of disease. Many African immunologists combine clinical work with research.

Why it matters in Africa

HIV remains the world's most significant infectious disease challenge and is concentrated in Africa. Understanding the immune mechanisms that control HIV infection is essential to developing effective vaccines and cures. Malaria vaccine development depends on immunology. The emergence of COVID-19 and the need for rapid vaccine development demonstrated that Africa needs its own immunology research capacity. Autoimmune diseases, often missed and mismanaged in Africa, affect millions of people, particularly women. Immunologists who choose Africa are working on some of the most important scientific questions of our time.

Your pathway in

Biology and Chemistry at secondary school are essential. Then either a medical degree leading to clinical immunology specialisation through the West African College of Physicians or equivalent, or a science degree followed by a PhD in Immunology for a research pathway. Several African universities including the University of Cape Town, the University of Nairobi, and the University of Ghana have strong immunology research programmes.

Skills you will need

Technical: Flow cytometry, ELISA and immunoassay techniques, cell culture, molecular immunology including PCR and sequencing, allergy testing, and immune deficiency assessment. Human: Scientific curiosity and the persistence to investigate complex biological questions, precision in laboratory technique, the ability to translate immunological findings into clinical or public health applications, and for clinical immunologists the communication skills to explain complex immune conditions to patients. Digital tools: Flow cytometry analysis software, bioinformatics tools for analysing immune datasets, laboratory information management systems, and scientific literature platforms.

A woman in this field

Prof. Koleka Mlisana

Kenya

Prof. Mlisana is a leading South African clinical microbiologist and immunologist. She has played a pivotal role in the Centre for the AIDS Programme of Research in South Africa (CAPRISA), where her work on the immune response to HIV has been instrumental in vaccine research. She has served as the Head of Microbiology at the University of KwaZulu-Natal and was a key leader in the laboratory response during the COVID-19 pandemic. She is a powerful advocate for strengthening the research pipeline for young African women scientists.

Take your first step

Biology is your most important subject at school – the immune system is one of the most fascinating topics in all of biology. Start with the basics: understand how vaccines work, how HIV destroys the immune system, and how the body recognises self from non-self. Khan Academy has excellent free immunology content. Look at the work of the African Academy of Sciences which highlights African scientists doing outstanding research including in immunology. If you can access science fair or biology olympiad competitions, pursuing them is excellent preparation for a research career.
