Ensuring that infants begin and continue receiving essential vaccinations can be particularly challenging in underserved communities.

Families may interact with community-based providers and traditional birth attendants even where their engagement with formal health facilities is less consistent. This creates an opportunity to explore whether community-level delivery mechanisms can help extend the reach of important primary health interventions.

The project therefore examined the feasibility of using community-based workers to distribute a simple reminder intervention designed to support infant immunisation.
