Platform for rapid immunological characterization of SARS CoV-2 variants in Kenya and the Eastern Africa Region

In plain English

AI plain-English summary

A network of hospitals and labs across Kenya and Eastern Africa will track how well existing antibodies—from vaccines and past infections—still neutralise new SARS-CoV-2 variants as they emerge. This matters because most variant surveillance in Africa has focused on genomics—spotting new mutations in viral genetic sequences—but has not kept pace with the functional consequences: whether those mutations actually let the virus evade immune defences. Without that immunological data, public health officials cannot predict whether a new variant will render current vaccines less effective, or whether booster campaigns need to be redesigned. If the platform succeeds, it will produce directly actionable health intelligence. When a concerning variant appears, the network can quickly tell policymakers whether antibody neutralisation has dropped, and by how much. This allows targeted adjustments to vaccine strategies, travel advisories, and public health measures—reducing both health harms and economic disruption from blunt, blanket restrictions. The project also includes a monoclonal antibody discovery pipeline, which could yield new therapeutic antibodies that work against multiple variants, strengthening the region’s preparedness for future outbreaks.

View original technical description
We propose to augment our well-established genomics surveillance infrastructure with a well-structured and coordinated platform for continuous immunological surveillance and characterization of emerging SARS-CoV-2 variants within Kenya and the Eastern Africa region. We will assemble a network of collaborating health facilities across Kenya and the Eastern Africa region to contribute genomic and immunology samples. Our current status as an Africa CDC/WHO-AFRO regional genomic reference laboratory has facilitated bidirectional sample and data sharing with Ministry of Health teams from Eastern Africa and will be a key feature of the immunology work. We will determine whether newly emergent variants exhibit substantial changes in their sensitivity to neutralization by antibodies induced by vaccination and natural infection, and consequently predict the likely impact on vaccine effectiveness. In addition, we will establish a monoclonal antibody discovery pipeline to rapidly identify variant specific or cross-neutralizing monoclonal antibodies. The network will therefore produce directly actionable health intelligence to support local and international public health policy adjustments to curtail the negative health and economic impacts of the virus.
