About the Project

This project aims to achieve 100% full immunization coverage in India, particularly among marginalized and hard-to-reach populations like tribal groups. It builds upon the success of existing immunization programs by addressing remaining gaps through Human-Centered Design (HCD).

While national coverage has improved significantly, substantial variations exist at the state and district level. This project focuses on Uttar Pradesh (Bahraich & Firozabad) and Meghalaya (Ribhoi & West Jaintia Hills) to bridge this gap and ensure "no one is left behind."

Our Approach: Behavioural Science for Improved Uptake

This project leverages behavioural science to understand the factors influencing vaccine confidence and uptake among tribal communities. We utilize two key frameworks:

• Capability, Opportunity, and Motivation – Behavioral (COM-B) model: This model posits that behavior is determined by three main factors:
  
  • Capability: The individual's ability to perform the behavior, including knowledge, skills, and physical capacity.
  • Opportunity: The environmental factors that influence behavior, such as resource availability, social support, and regulations.
  • Motivation: The individual's desire to perform the behavior, including beliefs about consequences, emotions, and social norms.

The COM-B model helps us identify where challenges lie within these factors for vaccine uptake.

• Theoretical Domains Framework (TDF): This framework provides a comprehensive taxonomy of 14 psychological domains that influence behavior, further broken down into 82 constructs

By combining the COM-B model and the TDF, we gain a deep understanding of the psychological and social factors influencing vaccine uptake among tribal communities allowing us to design targeted interventions that address specific barriers and promote positive behavior change.
