  • Implementing long-acting injectable HIV pre-exposure prophylaxis services at private pharmacies in Kenya

    Open Access•Stephanie Roche, Kevin Kamolloh et al.•ARTICLE•BMJ Global Health•2026

    INTRODUCTION: Maximising the impact of new and forthcoming long-acting injectable HIV pre-exposure prophylaxis (PrEP) products will require novel delivery approaches that widen accessibility and prioritise clients' needs and preferences. To understand the potential barriers and facilitators to delivering injectable PrEP via private pharmacies in Kenya, we conducted qualitative formative research. METHODS: From July to September 2023, we interview…

  • Low HIV-risk aligned discontinuation among HIV pre-exposure prophylaxis users within public HIV clinics in Kenya

    Open Access•Njeri Wairimu, Kenneth Ngure et al.•ARTICLE•PLOS Global Public Health•2025

    Adherence to oral HIV pre-exposure prophylaxis (PrEP) is crucial for its effectiveness, however, studies have shown that PrEP use wanes within the first six months. We sought to understand reasons for discontinuation among individuals previously accessing PrEP from HIV clinics. Between November 2020 – January 2023, we conducted a mixed methods sub-study within a programmatic study to improve the efficiency of PrEP delivery in four public HIV clin…

  • Acceptability and feasibility of a urine-based tenofovir adherence assay for monitoring and providing feedback on PrEP adherence in Kenya

    Phelix Okello, Jennifer Velloza et al.•ARTICLE•AIDS Care•2025

    Objective measures of oral PrEP adherence - especially point-of-care (POC) measures that enable real-time assessment, intervention, and feedback - have the potential to improve adherence. Our team previously developed and validated a novel urine-based POC metric of PrEP adherence. In this study, we sought to determine whether this assay is acceptable and feasible among women taking PrEP and PrEP providers in Kenya. We conducted a trial comparing …
