A framework to identify the children who missed basic vaccines in developing countries

Childhood vaccination is a cornerstone of public health, safeguarding children against life-threatening diseases. However, in many developing countries, a significant number of children either miss their routine vaccinations or receive incomplete doses, leaving them vulnerable to preventable illnesses. This chapter presents a framework aimed at addressing this pressing issue. It encompasses a summary of state-of-the-art studies examining the factors contributing to missed basic vaccinations, the synthesis of effective strategies for identifying and intervening in cases of vaccine gaps, and a discussion on the potential application of advanced technologies such as artificial intelligence, blockchain, and smartphone apps, within this context. Drawing on a wide range of research, this framework offers a systematic approach to locating and supporting children who have missed essential vaccinations. By addressing both the root causes and the potential solutions using advanced technologies, it provides a valuable resource for healthcare professionals, policymakers, and organizations committed to improving vaccination coverage in impoverished regions. Ultimately, this framework underscores the importance of equitable access to life-saving vaccines for all children, regardless of their socioeconomic status or geographic location, in our collective pursuit of global health equity.
