Situation

Cervical cancer remains one of the most preventable yet under-addressed health risks for women in India. With the introduction of HPV vaccination at scale, partners including Girl Effect, supported by Gavi, the Vaccine Alliance and aligned with Ministry of Health and Family Welfare, needed a digital SBCC solution that could address vaccine hesitancy, cultural stigma, and gendered household decision-making. Traditional awareness campaigns lacked personalisation, accessibility, and measurable behavioural outcomes.

Assignment

Design a scalable, multilingual conversational system capable of increasing HPV vaccine awareness and parental confidence while generating measurable engagement metrics aligned with donor reporting and national immunisation priorities.

Approach

A WhatsApp-based chatbot, TeekaTalk, was designed as a behaviour change engine rather than an FAQ tool. Persona-driven journeys reflected household dynamics—emotionally supportive storytelling flows for mothers and quick decision pathways for fathers. Branching “choose-your-path” narratives guided parents through scenarios, myth-busting content, vaccination centre access, and reminder systems. Universal design principles ensured usability across Hindi, English, and Hinglish interfaces with low reading complexity and minimal cognitive load.

Result

TeekaTalk created a measurable SBCC infrastructure capable of tracking engagement, intent-to-vaccinate signals, reminder opt-ins, and vaccination centre searches. The architecture demonstrates how conversational systems can bridge public health policy, community trust, and scalable behaviour change—offering a model adaptable to immunisation, maternal health, and adolescent wellbeing programmes across the Global South.
