Dr. Jacqueline Weyer

Jacqueline Weyer is a South African virologist and infectious diseases researcher associated with the National Institute for Communicable Diseases. Her work focuses on zoonotic and emerging pathogens, with particular expertise in rabies and other lyssaviruses, vector-borne diseases, and high-consequence viral infections affecting both humans and animals across the region.

Her publications highlight leadership in molecular epidemiology and genomic characterization of pathogens, including rabies virus lineages, novel bat-associated lyssaviruses, Rift Valley fever virus vectors, mpox, and Candida auris outbreaks. Through phylogenetics, surveillance data, and whole-genome sequencing, she advances understanding of transmission dynamics, cross-border spread, and outbreak investigation in complex ecological settings.

Weyer also contributes to vaccine impact evaluations and public health policy discussions, as reflected in work on pneumococcal conjugate vaccines and health research governance in Africa. Her research strengthens laboratory-based surveillance systems and informs evidence-driven strategies for disease control, preparedness, and response in resource-constrained contexts.
