Abstract
South East Asia carries 83% of the global burden of Plasmodium Vivax (P.vivax) malaria[1], and has increasing development of multi-drug resistant P.vivax 1,[2]. Standard control measures have proven unsuccessful at combating P.vivax, leading the Mahidol Oxford Tropical Medicine Research Unit (MORU) in conjunction with Mahidol University to propose and receive funding to conduct a Controlled Human Malaria Infection Study (CHMIS) to test vaccines, identify correlates of protection and test novel drugs for P.vivax malaria. Due to its study design CHIMS creates a multitude of ethical and regulatory challenges [3],[4].
This thesis was a qualitative case study to examine the role and potential value of a community and stakeholder engagement strategy for the establishment of a P.vivax CHMIS by the Mahidol Oxford Tropical Medicine Research Unit (MORU) in Bangkok Thailand. The aim of the study was to examine: 1.) the unique challenges that arose during the planning and creation of a CSE strategy for a P.vivax CHIMS, 2.) how CSE was used to address these challenge; and 3.) the value of utilizing CSE in the development of CHIMS for P.vivax. Seven in-depth interviews and nine informal interviews were conducted with MORU and Mahidol staff, along with a focus group discussion with global ethical researchers and Thai ethics committee members. Additional data were collected through field observations and literature reviews. Data analysis was conducted using grounded theory and qualitative analysis methods of memo writing, analytic code creation, clustering, and freewriting. Findings showed that a P.vivax CHIMS had unique societal, social and ethical challenges compared to other clinical trial studies and that community and stakeholder engagement functioned as a “de –risking” mechanism for the P.vivax CHIMS in Bangkok, Thailand.
