Immunization, Vaccines and Biologicals

An integrated supply chain in Senegal

Demonstrating technologies and system interventions

In the last ten years, Senegal has successfully increased vaccine coverage, expanding important immunizations to children across the country. However, the country’s vaccine supply chain has now reached its saturation point, making it difficult to introduce new vaccines that require robust systems for transportation and storage. In response to these challenges, project Optimize, a collaboration between the World Health Organization and PATH, is working with the Senegal Ministry of Health to identify vaccine supply system interventions that can be piloted now in preparation for the next 10 to 15 years.

Delivery teams may also include a supervisor and cold chain technician to provide supportive supervision to health care workers and ensure that the equipment is running efficiently.

Our work is proceeding in two phases. First, we evaluated Senegal’s existing supply system and made recommendations for strengthening the supply chain as more vaccines and health products are introduced in the country. Now we are collaborating with the Senegal Ministry of Health on a demonstration project that could serve as a model for the entire country.

Through this collaboration, the Senegal Ministry of Health is evaluating a new integrated supply chain model in the Saint Louis region. The project aims to ensure that vaccines and other health commodities are consistently maintained at appropriate stock levels. If these interventions are determined feasible, the Ministry of Health intends to scale up the work and a road map for scale-up is currently being developed. In addition, the Optimize team is collaborating with the Ministry of Health to establish a long-term vision for the supply and logistics systems of other immunization and health care services.

Our approach includes the following activities:

  • Integration of the supply chains for public-sector vaccines, drugs, and other health products from the central to regional level, managed by the National Procurement Pharmacy (PNA).
  • Demonstration of a “moving warehouse” operated by the Regional Supply Pharmacy and the Saint Louis office of the PNA and staffed with delivery teams that bypass the district storage level to visit health facilities directly, replenishing stock and providing technical assistance and supportive supervision as needed.
  • Testing a logistics management information system that links moving warehouse operations information to existing information systems, enabling fast and accurate flows of data from district to regional and central levels.
  • Improving the reliability of vaccine storage at both the regional level and at hard-to-reach health posts through the implementation of a hybrid solar and grid-electric system, including solar battery free refrigerators with remote temperature monitoring alarm systems to power the regional vaccine store.
  • Modeling the supply system in order to generate cost data and simulate various supply chain scenarios for the future.

Senegal moving warehouse photobook

In March 2011, the Government of Senegal began using a "moving warehouse" to transport vaccines and vaccine supplies from regional stores directly to 110 district stores and health posts on a monthly basis in the Saint-Louis region. This photo set explains how the moving warehouse works and shares results from an Optimize-supported pilot demonstration of the moving warehouse from 2000 to 2012.

Optimize Senegal repport

This report presents the results of demonstration projects and other activities undertaken in Senegal as part of a partnership between project Optimize and the Senegalese Ministry of Health (MOH). Between 2009 and 2012, Optimize collaborated with the MOH to demonstrate innovations in the supply chain that can help the national immunization program to meet the demands of an increasingly large and costly portfolio of vaccines.

Improving vaccine delivery through moving warehouses

Project Optimize is collaborating with the Senegalese Ministry of Health to implement and validate a "moving warehouse" that will streamline the vaccine supply chain from the regional to the peripheral level. A moving warehouse is a truck composed of delivery teams that visit each health facility, check stock levels, and replenish stock as needed.

Senegal: Integrating and streamlining health supply chains

This document describes how project Optimize is collaborating with the Senegalese Ministry of Health to demonstrate innovations in the supply chain that can help to increase efficiency and improve performance, preparing the country for the introduction of new vaccines in the future.

Harnessing solar energy for health needs

Many health facilities in remote areas operate without grid electricity, have unreliable electricity, or find that using electricity is too costly. In these settings, solar energy is a promising solution for powering the storage and transportation of vaccines and heat‐sensitive drugs at controlled temperatures. Project Optimize has been working with public and private partners on several solar technologies tailored to the following local electrical power conditions: unavailable or unreliable power, intermittent power, and reliable power.

Point of service data to drive vaccine supply chains

This fact sheet outlines the different approaches that project Optimize is testing to demonstrate that a consumption‐based system that uses service-delivery-level data can have a beneficial impact on inventory management, stock levels, and vaccine wastage.
