Pharmacy-based Provision of Pre-exposure Prophylaxis (PrEP) for Adolescent Girls and Young Women in Tanzania

This study will evaluate the effectiveness of pharmacy-based PrEP implementation for YW in the Lake Zone, Tanzania. Four models for pharmacy-based PrEP delivery will be evaluated and compared to pharmacies that do not provide any PrEP services for 9 months (phase I of the implementation study). The PrEP implementation models build on one another with each pharmacy-based PrEP model providing progressively expanded access to PrEP in pharmacies for YW.

All PrEP implementation models will be implemented alongside a girl-friendly loyalty program (Mwotaji Program) offering free sexual and reproductive health products including HIV self-test kits, pregnancy tests, and contraceptives.

Comparison: Standard facility based PrEP services to YW.

After 9 months (phase II), all pharmacies will implement the best performing PrEP model, based on findings from phase I. Moreover, all 50 pharmacies will implement cost-sharing. The investigators will assess acceptability, feasibility, and potential for sustainability of the pharmacy-based PrEP models. Two cost-sharing approaches will be randomized across the CRPS in a 3:2 ratio:

• Fee-for-service model: PrEP refills provided for 500 Tanzanian Shillings (TZS) each, a standard cash-based transaction for user fees, benchmarked with data from prior studies.
• Loyalty hybrid model: PrEP refills provided for free with any shop purchase or a fee of 500 TZS without a purchase.

The implementation study comprises a cohort study (parent study) conducted among YW and three sub-studies:

• Household survey (cross-sectional survey conducted with YW)
• Pharmacy surveys (surveys conducted with pharmacy staff)
• Stakeholder surveys (surveys conducted with health facility staff and governmental stakeholders)
