Missed Opportunities for Vaccination (MOV)

Written by


A missed opportunity for vaccination (MOV) refers to any contact with health services by a child or adult who is eligible for vaccination, which does not result in the person receiving one or more of the vaccine doses for which he or she is eligible. When countries observe that their vaccination coverage is decreasing or stagnating, they seek alternative strategies to explore the reasons and design tailored strategies to address them. The MOV strategy, which includes the 1) Planning Guide to Reduce Missed Opportunities for Vaccination, 2) Methodology for the Assessment of Missed Opportunities for Vaccination and 3) Intervention guidebook for implementing and monitoring activities to reduce Missed Opportunities for Vaccination, was designed to help decision-makers and national or subnational programme managers reduce MOV. The MOV strategy aims to increase immunization coverage by simply making better use of existing vaccination sites and promoting synergy between different maternal and child health programmes. The MOV strategy answers three important questions:

  • How many opportunities were missed?
  • Why are these opportunities being missed?
  • What can be adjusted or done differently?

Once these questions have been addressed, the MOV strategy aims to link and translate the MOV findings into actionable solutions and interventions to reduce MOV, especially at the facility level where vaccination services are provided.
