PrEP Method Switching: Will it Yield Greater Coverage of HIV Protection? Applying Lessons Learned from Family Planning to Guide Future Research in the Context of PrEP Choice.

Purpose Of Review: Despite the growing availability of oral PrEP, coverage remains suboptimal. Through the introduction of additional PrEP methods, including vaginal rings and long-acting injectable formulations, health systems globally are on the cusp of offering PrEP methods that vary by route of administration, efficacy, and frequency of use. With PrEP choice, it will be important to explore PrEP use patterns to better understand how the ability to choose and switch products affects coverage and continuation.

Defining principles for a choice-based approach to HIV prevention.

The HIV prevention landscape is on the cusp of an unprecedented era of multiple biomedical prevention products available for distribution. Several HIV prevention options, such as oral pre-exposure prophylaxis (PrEP), dapivirine vaginal rings, and injectable cabotegravir for PrEP, are becoming more widely available. Although the future HIV prevention market promises to be rich in options, it would benefit from a core set of principles that uphold choice in all phases of product development, assessment, and introduction.
