Purpose of review: Pre-exposure prophylaxis (PrEP) is highly efficacious for preventing HIV. Demonstrations worldwide show growing acceptability with nonoral formulations in the pipeline. Despite these successes, oral PrEP scale-up in sub-Saharan Africa (SSA), the region hardest hit by HIV, remains sub-optimal. This review details emerging practises and addresses challenges in PrEP scale-up and delivery within SSA.
Recent findings: PrEP scale-up varies across SSA. Some countries face implementation challenges, whereas most have not applied for or received regulatory approval. As governments balance treatment and prevention costs, PrEP advocacy is growing. Demand has been slow, because of low-risk perception, HIV treatment conflation or poor information. Challenges in SSA are markedly different than elsewhere, as delivery is targeted to generalized heterosexuals, rather than only key populations. SSA requires public sector engagement and innovative delivery platforms.
Summary: PrEP scale-up in SSA is sub-optimal, hindered by regulatory processes, implementation challenges, poor community engagement and inadequate funding. Approaches that acknowledge overburdened, under-resourced health sectors, and seek opportunities to integrate, task-shift, decentralize and even de-medicalize, with a tailored approach, while campaigning to educate and stimulate demand are most likely to work. Solutions to oral PrEP scale-up will apply to other formulations, opening new avenues for ARV (microbicides and injectables) and non-ARV-based (future vaccine) biomedical prevention provision.
