Poor data quality resulting from routine immunization (RI) that is centered on a registry-based reporting approach can influence improper management of resources which hampers the data value of vaccine monitoring and RI services at primary healthcare centers. The present study has attempted to address these data-related predicaments by examining selected primary healthcare centers within Edo State for their mode of RI and vaccination data. It has proposed an architectural framework for dashboarding data services for vaccines and RI. A qualitative research approach was employed for data gathering and the prototype software development methodology was adopted for engineering the dashboard solution. To trace users’ experiences on the solution for vaccine and RI data integration services, user-centric evaluation was simulated upon request/response for both mobile and desktop platforms to mimic real primary healthcare workers while assessing the performability of the prototype dashboard solution. The evaluation results and analysis further established that the implemented and evaluated dashboard solution is user-centric and highly supportive of integrating data and information on vaccine and RI services across primary healthcare centers and local government areas towards quality data and efficiency in service delivery. Thus, the study underlines the architectural
framework as an integral component of the National Primary Healthcare Development Agency to ensure quality data-driven decisions while improving on the centralized registry-based approach of the national immunization initiatives.
