Community Engagement in Biomedical HIV Prevention Trials
Summary
Community engagement is integral to the ethical conduct and scientific success of biomedical HIV prevention trials. Such engagement encompasses sustained, bidirectional dialogue between researchers and the communities affected by HIV, ensuring that study designs, consent processes and intervention strategies address local needs and values. Practical mechanisms range from community advisory boards and stakeholder consultations to participatory mapping of trial sites and tailored information campaigns. Through these practices, communities contribute to shaping research questions, refining protocols, promoting trial literacy and fostering trust. Engagement reduces misconceptions, mitigates rumours and supports recruitment and retention by aligning trial procedures with cultural norms and individual concerns. Equally, it enhances ethical oversight by clarifying benefit‐sharing arrangements, identifying potential harms and establishing feedback loops for adverse events. Globally, diverse settings—from urban informal settlements to rural regions—have demonstrated that robust engagement strengthens social licence for HIV prevention trials, underpins regulatory approval processes and ensures that findings translate into acceptable, scalable interventions. As novel technologies such as long-acting antiretroviral formulations and antibody-based prophylactics advance through clinical testing, community engagement remains essential to balancing scientific objectives with respect for autonomy, inclusivity and equity.

Community Engagement in Biomedical HIV Prevention Trials publication trend
The graph below shows the total number of articles in community engagement in biomedical hiv prevention trials across all publications each year (not limited to Nature Index journals).
Technical terms
Community Advisory Board (CAB): A formal group of community representatives who provide guidance on trial design, consent materials and outreach strategies to ensure research aligns with local values and needs.
Good Participatory Practice (GPP): International guidelines that outline principles and benchmarks for stakeholder engagement throughout the lifecycle of HIV prevention trials, from protocol development to dissemination.
Trial literacy: The level of understanding among community members about the objectives, procedures and potential risks and benefits of a clinical trial, which influences informed consent and trial participation.
