Green Earth Initiative
Project Overview

This project explores how demand-side incentives can support families to access routine immunisation services, especially for zero-dose and under-immunised children.


CMS HARD Foundation works with partners to test practical models such as transport support, facility-level funding, and other non-cash incentive approaches that reduce barriers and encourage timely vaccination.


Key Objectives:

  • Reach zero-dose and under-immunised children

  • Reduce practical barriers to vaccination

  • Test incentive models through structured research

  • Support evidence for scalable immunisation strategies

How we make change
Checkmark

Evidence-based design

We use research and implementation learning to understand which incentive approaches work best in different contexts.

Making vaccination easier for families

When families face cost, distance, and access barriers, even simple support can make a difference. This project helps generate practical evidence on how incentives can improve immunisation access and reduce missed opportunities.
