DigiTaPP Study:
Digitally Driven Risk Networks &
HIV Vaccine Preferences

Overview
YRG MERF participated in the DigiTaPP (Digitally-driven Target Product Profile) study aimed at informing user-centric HIV vaccine profiles by understanding the evolving dynamics of sexual risk networks - both online and offline - among adolescents and truck drivers in India. The study was conducted in parallel across South Africa, Uganda, and India.

Activities
Activities
Phase 1
In-depth interviews (65 in total) in Delhi, Mumbai, Chennai with Adolescent Girls & Young Women (AGYW), Adolescent Boys & Young Men (ABYM), and Truck Drivers (TDs).
Establishment of a dedicated site offering nutritious meals, counselling for mental health and substance use, basic clinical care with on-site diagnostics, hygiene facilities, and Opioid Substitution Therapy (OST) in partnership with Delhi SACS.
Phase 2
Data collection on digital behaviours, risk perceptions, and vaccine preferences in the same sites and populations.
Daily operations include enrolment, proactive engagement in services, and linkages to social protections like Aadhaar cards, pensions, and food rations.
Outputs
Outputs
Insights on digital versus physical networks, low awareness of PrEP/PEP, and vaccine preferences (e.g., 6–8 shots over 2.5 years, high efficacy, priority access)
Communication and access recommendations for culturally sensitive strategies

Outcomes
Tailored Target Product Profiles (TPPs) aligned with behavioural and digital trends.
Enhanced strategies for HIV vaccine rollout, addressing low-risk perceptions and improving acceptability among high-risk groups.
