Improving data quality and use in an electronic immunization registry: A case study from Vietnam

Building an electronic immunization registry (EIR) in Vietnam required years of hard work, patience, and perseverance from people at all levels of health care systems across the country. In the years since its inception, emphasis has been placed on the quality of data entered into the system and the subsequent use of that data at all levels to inform evidence-based decisions.

This case study outlines the aspects of strengthening data quality and use in the National Immunization Information System (NIIS) through the Introducing Digital Immunization information systems–Exchange And Learning from Vietnam (IDEAL) project. It details how, with the strong collaboration of key partners, Vietnam has implemented these activities within the system of operation today. We hope that this case can be studied, learned from, and ultimately improved upon by public health practitioners and governments with similar socioeconomic contexts that want to create their own EIR with high-quality data and achieve the benefits from the use of such data.
