Multi-dose vials versus single-dose vials for vaccination: perspectives from lower-middle income countries

The choice of the vaccine packaging type either as single- or multi-dose vial is a crucial determinant of vaccine coverage. The experience of vaccination strategies in lower-middle-income countries suggests that multi-dose vaccine vials translate into greater economic-logistic advantages due to lower packaging and storage costs with significant environmental benefits accrued from reduced medical waste generation. However, the use of multi-dose vials is associated with a theoretical risk of contamination particularly from human error. Moreover, the overall economic advantage of multi-dose vials is contingent on the reduction of the extent of vaccine wastage associated with their use. Robust data collection for monitoring of vaccine wastage rates and adverse effects following immunization is therefore needed to understand the extent of economic benefit and risks involved with multi-dose vial use

The effectiveness of a dose based reporting tool in reducing vaccine wastage at primary care clinics in Delhi, India: an operational research study

Minimizing vaccine wastage and associated costs is considered a key target for appropriate vaccine management. In India, the Rotavirus Vaccine (RVV) (2019) and the fractionated injectable polio vaccine (f-IPV) (2016) are more prone to wastage with high procurement costs. In this operational research study, we determined the effectiveness of a (self-designed) dose based reporting tool (DBRT) in reducing vaccine (f-IPV and RVV) wastage at primary care facilities in India during December 2019 to March’ 2020. Data reports of all the immunization sessions conducted at three primary care facilities were analyzed to calculate the wastage rates of the RVV and the f-IPV for the following periods: (1). Period of initiation (August-November’ 2019) (2). Pre-intervention with sensitization of healthcare providers (December’ 2019-January’ 2020) (3). Post-intervention after application of the DBRT. Intervention: The DBRT is a paper-based reporting format that assigns a unique code to each RVV and IPV vial. The health facility is required to report the total doses administered from each coded vial during every immunization session by updating it on the assigned reporting format. Pre-intervention, the average monthly wastage of f-IPV was 23.5% and of the RVV ranged from 18%-31%. Post-intervention, on using the DBRT, the monthly wastage of both RVV and f-IPV dropped significantly to 8.6% and 11.4%, respectively. During the subsequent month, the IPV wastage further decreased to only 4.7%. In conclusion, the DBRT reduces vaccine wastage in government primary care facilities by enabling a paper audit trail that promotes responsiveness and accountability among healthcare workers directly involved in vaccine administration
