WHO: INTERVENTION GUIDEBOOK TO REDUCE MISSED OPPORTUNITIES FOR VACCINATION

Missed opportunities for vaccination (MOV) include any contact made with health services by a child (or adult) who is eligible for vaccination, but which does not result in the individual receiving all the vaccine doses for which he or she is eligible. Today we are vaccinating more children than ever, yet millions of children still miss out on routine vaccinations. National immunization programmes continue to seek evidence-based strategies to understand the underlying reasons and to design tailored approaches to address them. 

Using a participatory mixed-methods approach, the MOV strategy provides step-by-step guidance on how to conduct a bottom-up root-cause analysis of bottle-necks in the immunization programme and to implement relevant interventions to address them. When applied appropriately, the steps outlined in the MOV guides have the potential to contribute to an increase in vaccination coverage and equity and an improvement in timeliness of vaccination
