The Dapivirine Ring: Key learnings from like-product introductions

Vaginal insertion and partial efficacy are two challenges that could affect the uptake and continued use of the dapivirine ring. Analyses of the introductions of other products that share similar characteristics provide useful lessons to inform planning for rollout of the dapivirine ring. This paper provides information for planners, implementers, funders, researchers, trainers, providers of technical assistance and others to build an agenda for introducing the dapivirine ring that addresses these two challenges.
