Vaccine wastage is a critical factor for those managing vaccine procurement to understand, in order to correctly quantify the amount of vaccine that is needed for purchase and hence reduce the risk of stockouts or overstocking.
Vaccine wastage may be due to avoidable causes, such as exposure to inappropriate temperature or damage of vials during transport, or unavoidable causes, such as the number of children presenting for immunization being fewer than the number of doses in a multi-dose vial.
Research shows that country-specific, vial-specific, and vaccine formulation specific wastage rates data are very limited and that with more expensive vaccines entering the system and the availability of the multi-dose vial policy, health workers are taking a more complex approach that acknowledges the tradeoff between coverage and wastage and takes into account issues of immunization equity.
PATH is undertaking a mixed methods study in Ghana to better quantify closed and open-vial wastage rates for vaccines used in the Expanded Program on Immunization (EPI) as well as understand the major drivers behind the occurrence of wastage and their impact.
The study includes collection of retrospective and 3-month prospective data on vaccine wastage and conducting interviews with EPI staff working at various level of the vaccine supply chain and service delivery level.
The study will also contribute in establishing methodologies for estimating context-specific wastage rates. The study supervisor will lead and coordinate the data collection activities in Ghana for this study.
This work will be done in collaboration and coordination with the Ghana EPI.
Specific duties and responsibilities :
This includes reviewing the data collected and taking steps to correct any data quality issues.
Conduct study supervision visits to health facilities and districts that are not either incorrectly and / or inconsistently reporting these data and work with the district vaccination officers to take corrective measures and obtain the data
