Aspro. Jenifer Vaughan

Jenifer Vaughan is a South African clinical haematologist and academic researcher affiliated with major Johannesburg academic hospitals and the National Health Laboratory Service. Her work centres on haematological malignancies in high HIV-prevalence settings, with a particular focus on diffuse large B-cell lymphoma and Hodgkin lymphoma. She integrates laboratory diagnostics with clinical outcomes research to address disparities in cancer care in resource-limited environments.

Her publications highlight the immunopathology and tumour microenvironment of HIV-associated lymphomas, including studies on cytokines, tumour-associated macrophages, peripheral immune cell profiles, and novel haematology analyser parameters as prognostic biomarkers. This body of work advances understanding of immune dysregulation, prognostic indicators, and therapeutic response, particularly in relation to rituximab use and survival outcomes in South African cohorts.

Vaughan has also contributed to research on diagnostic stewardship and cost-effective testing strategies, demonstrating the value of essential immunohistochemistry and molecular tools in constrained settings. Additional studies span opportunistic infections, bacteremia biomarkers, chronic myeloid leukaemia, and collaborative work in inborn errors of immunity. Collectively, her scholarship strengthens laboratory-clinical integration and informs context-appropriate oncology practice in sub-Saharan Africa.
