Abstract
Description
This interview profile traces the career of South African paediatrician, scientist and public health leader Glenda Gray, highlighting her contributions to HIV prevention, treatment research and health advocacy in South Africa. Reflecting on her experiences during apartheid and the emergence of the HIV epidemic, Gray describes how clinical practice, activism and scientific research became intertwined in her work. The interview reviews the establishment of pioneering HIV services and research programmes in Soweto, including initiatives focused on prevention of mother-to-child transmission, counselling, infant feeding choices and access to antiretroviral interventions. It also discusses the challenges posed by HIV-related stigma, policy resistance and resource constraints, as well as efforts to strengthen evidence-based responses to the epidemic.
The article further examines Gray’s leadership in HIV vaccine research, including major clinical trials conducted through the South African Medical Research Council and international research partnerships. She reflects on the scientific lessons derived from unsuccessful vaccine trials, advances in immunology and biotechnology, and the continuing search for an effective HIV vaccine. The interview also considers broader themes of research capacity-building, public engagement, ethical decision-making and innovation in global health. Finally, Gray discusses emerging priorities, including antimicrobial resistance and paediatric health, emphasizing the importance of sustained scientific investment, collaboration and equitable access to health technologies.
