Enhancing the Effectiveness of Sustainability Partnerships: Summary of a Workshop XVI Public-Private Partnerships and Pro-Poor Livestock Research: The Search for an East Coast Fever Vaccine David J. Spielman International Food Policy Research Institute, Addis Ababa ABSTRACT Livestock plays a critical, but often overlooked, role in the livelihoods of small-scale, resource-poor households in the developing world. Of the 1.3 billion people living in absolute poverty worldwide, some 678 million of them are livestock keepers. Their holdings of cattle, buffalo, sheep, goats, pigs, and poultry represent valuable stores of wealth while also serving as irreplaceable sources of income, insurance, fertilizer, energy, and nutrition. In sub-Saharan Africa, the dependence on livestock is particularly acute among smallholders—a broad grouping that refers to small-scale farmers, pastoralists, and those whose livelihoods combine both crop cultivation and livestock keeping. Thus, livestock improvement is a potentially powerful means of promoting sustainable development and reducing poverty in the region. This paper examines a research project designed to bring both public and private expertise to bear on the development of a vaccine for East Coast Fever (ECF), a devastating tick-borne bovine disease found throughout eastern, central, and southern Africa that is caused by the Theileria parva protozoa. Some 28 million cattle in the region are at risk of the disease, with at least 1 million cattle dying from it every year. In economic terms, the production losses caused by ECF-related morbidity and mortality are estimated at approximately US$300 million. The project, headed by the International Livestock Research Institute (ILRI), based in Nairobi, Kenya, sought to develop an experimental

Enhancing the Effectiveness of Sustainability Partnerships: Summary of a Workshop multicomponent subunit vaccine against ECF that could be shown to be protective to cattle in laboratory trials. The project’s long-term goal was to generate a safe, efficacious affordable and easily deliverable ECF vaccine in partnership with a commercial company. The key to success was identifying antigens that caused an immune response in the host cattle. This was to be pursued by sequencing the Theileria parva genome, cloning individual genes from the parasite, subjecting them to immunological assays, and determining which genes code for antigens are likely to confer immunity in the host cattle. The successful subunit vaccine would be one that incorporated sections of the Theileria parva DNA that, when injected into cattle, would confer immunity without infecting them with ECF. Success required a range of expertise and resources. So, beginning in 1999, ILRI set out to develop a global partnership to sequence the Theileria parva and conduct research that would lead to the development of an effective subunit vaccine. Beginning in 2001, ILRI enlisted the participation of The Institute for Genome Research (U.S.A.), a global leader in genome sequencing, along with the Ludwig Institute of Cancer Research, the University of Victoria (Canada), Oxford University (UK), the Centre for Tropical Veterinary Medicine (UK), the Weizmann Institute of Science (Israel), and the Kenya Agricultural Research Institute. In the same year, ILRI enlisted the expertise of Merial Ltd., a global leader in the animal health field, to draw on the company’s experience in field of vaccine development and product deployment. With Merial’s participation, the project team was able to develop an experimental vaccine. But while the testing with live cattle did generate the desired immune response—protection against ECF in cattle—the response occurred in only 30 percent of the cattle tested. Without this critical proof of concept, further partnership-based research effectively came to an end in 2007. Despite these discouraging outcomes, research on an ECF vaccine continues. Under the leadership of the Global Alliance for Livestock Veterinary Medicines (GALVmed), efforts are underway to form a new consortium to continue to the research and secure funding. Importantly, the project also generated several unintended consequences that will likely promote further research on an ECF vaccine. First, the project has encouraged several organizational innovations (e.g., new approaches to contracting, communicating, and intellectual property management) within ILRI and its partners to help bridge the gap between public and private sector researchers in future partnerships. Second, the project has put forth methodologies of vaccine antigen identification and evaluation that several research organizations are exploring, thus validating the project’s work and laying the ground for continued investment in ECF vaccine development.

Enhancing the Effectiveness of Sustainability Partnerships: Summary of a Workshop Third, the project has provided its partners with insights on how to better manage collaborative projects, including insights on when and how to end a project when it simply isn’t producing the desired results. In summary, the ECF vaccine development partnership is a potentially replicable model for other public–private research collaborations. It represents an innovative response to complex problem-solving tasks that require engagement with a range of diverse organizations and capabilities. It also offers an invaluable lesson on when to terminate a project—a decision rarely taken lightly by researchers or investors.
