Abstract

Objectives: Determining the vaccine wastage rate in Expanded Programme of Immunization and related factors in the southern provinces/cities in 2021. Method: Descriptive cross-sectional study design was carried out on 90 commune health stations in three provinces of Lam Dong, Binh Duong and Vinh Long through systematic stratified sampling method from provincial, district and commune levels. Result and conclusion: Measles vaccine wastage rate is 31.8%; MR 34.4%; DPT-VGB-Hib 0.7%; OPV 24.6%, DPT 56.3%; VAT 62.9%. The more the vaccines are packed with doses, the higher the wastage rate, which is correlated with the population, the number of subjects, the number of vaccination sessions, the topography, knowledge of training, and the practice of vaccine storage. The single dose DPT-VGB-Hib vaccine is less dependent on these factors. Main reason for canceling whole bottles was overdue 61%, followed by broken bottles 17.5%. Multi-dose vaccines have a higher waste rate than single-dose vaccines, the more doses the vaccine is packed, the higher the waste. The vaccine wastage rate is high in mountainous and midland geographical areas, low population, low vaccination population, these factors are correlated with each other. Meanwhile, single-dose vaccines do not depend on the above factors, depending on the storage and transportation procedures and the management skills of the warehouse staff of the warehouse staff and the up-line vaccination managers. Expiration is the major cause of bottle cancellations.
