About Us
The SABII research group are a team of researchers who build knowledge and capacity in social and behavioural science to strengthen vaccination programs around the world. We:
- Apply a broad range of social sciences to improving vaccine uptake, systems, programs and process;
- Empower people to make quality decisions at an individual, community and population level;
- Illuminate the value and contribution of social science to immunisation programmes
- Embed social science expertise in decision making.
