mHealth is the use of mobile devices and communication technologies for healthcare researches and practices. The widespread use of smartphones, the growth of mobile application development and the increasing demands of users have promoted the development, and usage of mHealth applications. In this work, a mHealth application called as ProvVacT is developed for tracking vaccination history. The main contribution of ProvVacT is that the application uses provenance information in order to trace the vaccination history. Provenance is used to refer to the origin of the information. Thus, it provides the trustworthiness of data. In this work, the ProvVacT application is based on an ontology-based provenance management approach in order to improve the quality, reliability, and reusability of vaccination data. Moreover, the vaccine information is also represented with an ontology-based approach.
