HIV prevention: better choice for better coverage.

Second-generation PrEP agents will have the potential to offer improved adherence and less frequent reminders once they have undergone further development and the delivery systems that will best support them have been established. In order to pursue global UNAIDS targets of reducing new HIV infections to fewer than 500,000 annually by 2025, and to ensure that all people have access to prevention options that meet their specific prevention needs, both early and next-generation PrEP options are needed.
