What this research studies

If I join, I'll be one of 200 people ages 15–34 getting PrEP care at clinics in Jackson, MS or in Providence/Boston, MA. I'll be randomly assigned to use the Viral Combat mobile game or to receive usual care, and the team will follow me over time to see how well I stick with my medication. The study will collect dried blood spots to measure drug levels and will use interviews and implementation methods to learn what helps clinics use the app. The aim is to see whether the game helps people stay on PrEP and how it can be rolled out in real clinics.

Who could benefit from this research

Good fit: Ideal candidates are people aged 15–34 who are starting or already taking PrEP at participating clinics in Jackson, MS or Providence/Boston, MA.

Not a fit: People who are not on PrEP, are outside the 15–34 age range, or who do not have access to a compatible smartphone or clinic visits may not benefit from this program.

Why it matters

Potential benefit: If successful, the app could help people take PrEP more regularly and lower their risk of acquiring HIV.

How similar studies have performed: A smaller randomized trial with 69 participants showed promising adherence improvements, but this larger multisite test is needed to confirm those results.
