Targeted Deployment of Long-Acting HIV Pre-Exposure Prophylaxis in sub-Saharan Africa: Modelled Impact on Infections and Programme Costs to 2050

Background Long-acting HIV pre-exposure prophylaxis (LAP) could transform HIV prevention in sub-Saharan Africa, but its public-health impact and value-for-money will depend on whether programmes can reach people at greatest risk. We quantified the potential impact and efficiency of targeted LAP deployment across sub-Saharan Africa. Methods We developed a deterministic, age-structured compartmental model of HIV among adults aged 15 years or older in African countries accounting for 98% of adults living with HIV in sub-Saharan Africa. Antiretroviral therapy (ART) was assumed to reach 95% coverag
