First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a mobile health program called PrEP Choice to help young people ages 13-24 start and stick with HIV prevention pills or shots. It also looks at whether taking the antibiotic doxycycline after sex (DoxyPEP) can prevent other sexually transmitted infections. About 200 participants who are at higher risk for HIV will be followed for up to 18 months to see if these tools work and are easy to use.
