Successful immunization programmes are built on end-to-end supply chain and logistics system. These systems enable effective vaccine storage, distribution, handling and management, ensure rigorous temperature control in the cold chain; and leverage logistics management information systems to promote resillient and efficient system performance. This system suffered setbacks due to COVID-19 pandemic and associated disruptions, COVID-19 vaccination efforts. The objective here is to perform SQL analysis using the vaccine supply and logistics dataset from (https://immunizationdata.who.int/), to determine the efficiency of the supply chain despite the setbacks.
