About this Publication:

The objective of the market scoping study was to assess the potential demand for the TSOL vaccine -oxfendazole combination and to gain a clear understanding of its potential for ‘private good’ marketing. It also assesses how the vaccine might influence product availability, supply mechanisms, price structure, competitiveness of products, profit margins, and the potential to sell these products to smallholder pig producers in Uganda. Eight separate market scoping studies have been conducted in Uganda’s Masaka, Bukedea, Kampala and Mukono districts targeted at different nodes of the pig value chain – namely consumers, traders, distributors, and drug stockists – and involved interviews, focus group discussions, a simulated egg experiment, choice experiments, and observation. Choice experiment is a multi-trait/multi-attribute stated preference method that assesses the value of single traits of a bundled good by using individuals’ stated preference in a hypothetical scenario. Due to the hypothetical nature of stated preference data in which the respondents are not bound by real life constraints, especially income in the choices made, there are tendencies for Willingness to Pay (WTP) values to be overestimated. Insights from the market scoping study showed that obtaining a premium price for immunized pigs is a strong incentive for farmers to vaccinate pigs for porcine cysticercosis. Additionally, the demonstrated preference for the TSOL18 vaccine with low administration costs (US$0.90 per pig) underscores a communal approach and preference for a one-dose TSOL18 vaccine. However, quality assurance is a concern for pig farmers, as expressed in their preference for a viability detector; the product manufacturer should take this into account. The TSOL18 vaccine-oxfendazole combination as presented is less likely to succeed as a private good. In addition, there is need for mass sensitisation about the control of T. solium cysticerciosis amongst stakeholders at all levels (including veterinarians, farmers, traders, butchers, consumers, animal health service providers, and policymakers). Necessary accompanying intervention measures along the value chain are explained.
