    Step into the world of viruses, bacteria and immune defences, and explore how this science guides the treatments and discoveries shaping human health

    Why study Infection and Immunity

    If you want to understand how the body fights illness and how science protects communities, Infection and Immunity is the perfect fit. You’ll explore how microbes cause disease, how the immune system responds, and how modern research is transforming treatments from vaccines to cancer immunotherapy.

    At Otago you’ll learn in a nationally recognised research environment, working alongside experts tackling real-world challenges like antibiotic resistance and emerging infectious diseases. Whether you’re driven to improve public health, investigate immune disorders, or help develop new therapeutics, this major gives you the tools and insight to make a meaningful impact.

    Career opportunities

    A Biomedical Sciences degree with a major in Infection and Immunity gives you strong scientific skills that lead into careers across health, research and biotechnology. Graduates often move into roles such as:

    • Research or laboratory positions in microbiology, immunology or infectious disease
    • Technical, regulatory or advisory roles in government, diagnostics or public health agencies
    • Science communication, education or medical writing in health and research sectors
    • Roles in biotech, pharmaceutical or health industries including product and support positions
    • Pathways into professional health programmes or postgraduate research (honours, masters', PhD)

    How you will learn

    You’ll learn through lectures, interactive tutorials and hands-on labs where you work with real microbes and analyse immune responses. From your second year you’ll be in research-active microbiology and immunology labs, gaining practical skills in culturing microbes, identifying pathogens and assessing immune function.

    By your third year you’ll dive into advanced topics like virology, immunotherapy and host–pathogen dynamics, often collaborating with peers and contributing to real research questions tackled on campus.

    Recommended high school subjects for undergraduate study

    You’ll do best in Infection and Immunity if you enjoy biology and chemistry, have a curious mind, and like solving problems. Previous experience in cell biology or microbiology is a big plus.
