Small Session Size and Big Vial Size: Operational Research Assessing Open Vial Vaccine Wastage at the Service Delivery Points in the Mandalay Region of Myanmar During 2018.

The World Health Organization (WHO) recommends immunization programmes to monitor vaccine wastage at storage and service delivery points. As there were no vaccine wastage assessments in Myanmar, we aimed to assess the vaccine wastage rates in the Mandalay region. We conducted a cross-sectional descriptive study with the inclusion of all immunization sessions conducted through the twenty randomly selected subcentres in the year 2018.
