Vacina Sim: development of paired mobile applications as an innovative strategy to improve vaccine adherence

This study aims to describe the development of a prototype of paired mobile applications for community health workers and users as a strategy to increase vaccination adherence. This is a methodological study of technological production using prototyping. The construction followed the human-centered design model, characterized by being a collaborative process focused on the person for the person. The development of the applications took place in four stages. The technical-scientific content of the application was built according to the recommendations and information from the National Immunization Program of the Brazilian Ministry of Health. The goal of the prototype developed for community health agents is to assist in managing the vaccines of users assigned to their microareas. The user application aims to provide reliable information about vaccines and alert reminders for vaccination adherence. The paired applications help in actively seeking users with incomplete vaccinations and applying other timely interventions, such as health education and self-management for health seeking.
