Increasing vaccine uptake in Sudan: Development of a web-based intervention (Preprint)

BACKGROUND WHO described Vaccine hesitancy in 2019 as one of the top 10 threats to global health in high, and low, and middle-income countries. Various communication approaches have been used to engage the public about vaccines and immunization such as mass media and e-health strategies. With the expansion in the use of communication technologies in health in recent years, websites have increasingly been used to support vaccine acceptance and demand and thus increase vaccine uptake. We recently established a web-based intervention called the Tat3im initiative website in Sudan. It aims to increase uptake of vaccines in Sudan by increasing knowledge and addressing issues related to vaccine hesitancy and vaccine safety in the Arabic language OBJECTIVE This article describes the processes that we used to develop and improve this website including the creation of its content. METHODS These processes were informed by using and combining three sources including, Garrett’s user experience framework as a basis for the development, the WHO Vaccine Safety Net's (VSN) criteria for good information practices (i.e. credibility, content (quality and quantity), design and accessibility criteria), and previous relevant research that assessed the local context in Sudan. RESULTS We found that using such evidence as well as combining the VSN's criteria and previous research findings in the five planes of Garrett's framework enabled us to cover many essential elements of user experience and to address issues related to the website’s strategy and content. CONCLUSIONS As the website may be limited due to the high rates of illiteracy as well as relatively low internet use in Sudan, we suggest using social marketing to promote the use of the website as well as monitoring and evaluating the website and users’ experience using different approaches such as visitor traffic and qualitative measures.
