BackgroundFor over 35 years, Africa has continued to host HIV vaccine trials geared towards overturning the HIV/aids pandemic in the continent. However, the methods of sharing the vaccines, when available remain less certain. Therefore, the study aims to explore stakeholders’ perspectives in the global South, in this case, Tanzania, on how HIV vaccines ought to be fairly shared.MethodsThe study deployed a qualitative case study design. Data were collected through in-depth interviews and focus group discussions with a total of 37 purposively (...) selected participants. This included researchers, institutional review board members, a policymaker, HIV/aids advocates, and community advisory board members. The data obtained were inductively and deductively analyzed.Results Findings indicate that HIV vaccines can be shared fairly under the principles of distributive justice (contribution, need and equality). Thus, contribution-based sharing ought to be utilized upon the necessity to prioritize vaccine access or subsidized trial benefits to host communities. Need-based sharing ought to be considered for non-host communities that are at an increased risk of HIV infection. Lastly, equal-based sharing would be useful at later stages of vaccine distribution or when the aforementioned principles are deemed morally inappropriate. However, none of the benefit-sharing approaches is free of limitations and a counterbalancing sense of unfairness.ConclusionFair sharing of HIV vaccines, when available, ought to be informed by the contribution, need and equality principles of distributive justice. Countries in the global south including Tanzania are likely to be prioritized during the distribution of the HIV vaccines due to their participation in HIV vaccine trials and due to the disproportionate HIV burden evident in the region.
