Bringing innovation to immunization supply systems in Viet Nam

Pioneering for the future

Optimize is improving the accuracy of and way immunization data is reported in Viet Nam.

With the expansion of electrical, telecommunication, and transportation networks in Viet Nam, the country is well poised to modernize its immunization supply system. Project Optimize, a collaboration between the World Health Organization and PATH, and Viet Nam’s National Institute of Hygiene and Epidemiology are working together to test new technologies and system designs that will support an immunization supply system expansion while also building a national long-term vision for immunization services.

Initially, efforts focused on the identification of the strengths and challenges of the supply and logistics systems of the country’s National Expanded Program on Immunization (NEPI) to better understand how the system could be improved. Demonstration projects were then designed in collaboration with Viet Nam’s Ministry of Health and NEPI to build upon the program’s capabilities and help manage the growing vaccination landscape. As these demonstration projects are implemented in 13 provinces, work is ongoing to develop a long-term vision for the country’s immunization supply systems.

Work in Viet Nam includes the following activities:

  • Introduction of long-term passive cooling devices for vaccine storage in commune-level health centers.
  • Introduction of battery-free solar refrigerators in district-level health centers for vaccine cooling without reliance on the electric grid.
  • Implementation of electronic vaccine tracking and immunization reporting through a new information system utilizing both web and mobile networks.
  • Introduction of a digital immunization registry to increase the accuracy and timeliness of immunization records.
  • Collaboration with NEPI as it adopts more rigorous procedures and training to improve vaccine management.
  • Collaboration with POLYVAC, a vaccine manufacturer and the Viet Nam Ministry of Health to encourage the use of vaccine vial monitors (VVMs) on measles vaccine as well as training and technical support on VVM use.
  • Comparison of costs and benefits of the existing vaccine supply chain with potential interventions such as those described above.

This photo set contains photographs of the installation and initial testing of two TrueEnergy BLF 100DC SureChill vaccine refrigerators in Viet Nam. The refrigerators were installed in May 2011, one in Thanh Ba district, Phu Tho province and the other in Thanh Phu district, Ben Tre province.


Optimize Viet Nam Project Report

This report presents the results of demonstration projects and other activities undertaken in Viet Nam as part of a partnership between project Optimize and Viet Nam’s Ministry of Health. The activities aimed to demonstrate innovations in the supply chain that can help meet the demands of an increasingly large and costly portfolio of vaccines.


Optimize Viet Nam Summary Report

Between 2010 and 2012, project Optimize collaborated with Viet Nam’s National Institute of Hygiene and Epidemiology to demonstrate innovations in the supply chain that can help to meet the demands expected as Viet Nam’s immunization program continues to grow. This summary report describes the activities undertaken in Viet Nam as part of the collaboration.


Viet Nam’s immunization registries

In Viet Nam, project Optimize worked with government and software partners to help introduce a digital immunization registry. This registry allowed the health system to better track children due for vaccination and shortened the time required for recording and reporting immunizations compared to the existing paper-based registry.


Cold chain temperature monitoring in Viet Nam: Monitoring ambient and cold chain temperatures during delivery of Human Papillomavirus vaccine

Human papillomavirus (HPV) vaccine is intended to prevent cervical cancer. As part of project Optimize, a two-year HPV vaccine demonstration project is being conducted to demonstrate how existing delivery systems can be adapted to successfully provide HPV vaccine to young adolescent girls. HPV vaccine is a strong candidate for out-of-the-cold-chain use given its characteristics of high heat stability and freeze sensitivity.


Breakeven analysis for various HPV vaccine presentations in Viet Nam and Uganda

The study highlighted in this project Optimize report uses a breakeven cost analysis to compare potential prices, wastage rates, and cold chain requirements for various human papillomavirus (HPV) vaccine presentations.


Monitoring ambient and cold chain temperatures during delivery of HPV vaccine in Viet Nam and Uganda

As part of project Optimize, a five-year human papillomavirus (HPV) vaccine demonstration project is under way in Viet Nam, Uganda, India, and Peru to generate evidence for government decision-making about successful vaccine delivery strategies to provide HPV vaccine to young adolescent girls. HPV vaccine is a strong candidate for storage and transport in a controlled temperature chain at temperatures higher than the standard 2° to 8°C cold chain storage.


Results from a survey of immunization stakeholders in Viet Nam regarding the presentation, packaging, and distribution of Human Papillomavirus vaccines

The purpose of this project Optimize survey was to obtain input from stakeholders within the Expanded Programme on Immunization in Viet Nam about issues and perceptions related to the storage, distribution, and delivery of the current and potential options for human papillomavirus vaccine presentation and packaging.


Keeping track of Viet Nam's vaccines

This evidence brief describes how project Optimize worked in Viet Nam with national, regional, and local partners to help introduce VaxTrak, a software program that allows users at various levels of the health system to track vaccine stock and report monthly immunization activity.


Assessment of the vaccine supply chain for fee-based immunization in Hanoi Capital and Ho Chi Minh City

The objective of this project Optimize assessment was to understand the structure, scope, and quality of the vaccine supply chain for fee-based immunization services and to provide recommendations for strengthening management and monitoring the quality of the vaccine supply chain for fee-based immunization.

Optimize Viet Nam phase I summary report: evaluating the vaccine supply chain in preparation for demonstrating future options in Viet Nam

Project Optimize is collaborating with the Vietnamese National Institute of Hygiene and Epidemiology on a series of activities designed to assess the opportunities and needs for strengthening the immunization system in Viet Nam. This document reports the results of assessments of the vaccine supply chain in Viet Nam, completed in March 2010.
