Despite rapid advances in the field of HIV prevention and treatment, unacceptably high global HIV incidence rates highlight the ongoing need for effective HIV prevention interventions for populations at risk for HIV acquisition. This article provides an updated review of the current data surrounding HIV prevention strategies, including treatment as prevention (TasP), preexposure prophylaxis (PrEP), and postexposure prophylaxis (PEP), as well as advances in sexually transmitted infection biomedical prevention. This review provides an overview of the multiple PrEP modalities that are available globally, such as oral PrEP, injectable cabotegravir, and the dapivirine vaginal ring, and describes their respective clinical trials, efficacies, and regulatory approvals.
