Caregiver and healthcare professional perspectives on drivers of routine immunisation uptake in East New Britain, Papua New Guinea: a qualitative study

This study highlights the challenge of identifying and including zero-dose children and their caregivers in research but still provides useful contextual focus points to enhance and inform tailored strategies to strengthen immunisation service delivery. These include strategies that improve bidirectional coordination and communication between healthcare professionals, community and religious leaders about routine immunisation, increase immunisation knowledge and strengthen community-based services for vaccine delivery.
