CARES: An adherence support intervention for multiple PREP methods among adolescent girls and young women in South Africa and Zimbabwe

NIH-funded research Research Triangle Institute · NIH-11191445

This project will offer counseling, biomarker feedback, and a menu of supports to help adolescent girls and young women in South Africa and Zimbabwe continue using oral, injectable, or ring-based PrEP.

What this research studies

This work will adapt the CARES adherence support program so it fits real-world clinics and adds injectable PrEP. The team will do formative research to tailor the program and then deliver counseling, adherence biomarker feedback, and optional supports like clubs, phone calls, and SMS. The adapted intervention will be tested in clinics in Zimbabwe and South Africa to see whether more young women stay on PrEP. The study compares results to prior trial findings to understand feasibility, fidelity, and acceptability in routine programs.

Who could benefit from this research

Good fit: Adolescent girls and young women in South Africa or Zimbabwe who are at risk for HIV and are considering or using oral, injectable, or ring-based PrEP.

Not a fit: People outside the study countries, those not in the target age range, or those not using or considering PrEP are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, more adolescent girls and young women could maintain protective PrEP levels and potentially avoid new HIV infections.

How similar studies have performed: A prior trial (MTN-034) that delivered CARES in research settings showed higher protective adherence for ring and oral PrEP compared with comparable studies, but this adapted program has not yet been proven in routine clinics.
