The present work describes the planning, implementation, and challenges to develop an international educational initiative among six partner institutions from four different countries, to build a collaborative teaching and learning environment. The course applies collaborative online international learning principles and is addressed to graduate students of universities from Brazil, Germany, Mozambique, and Kosovo. A pilot curriculum was developed with modules on intercultural competence, interprofessional and collaborative practice in One Health; One Health; healthcare, surveillance, and One Health; bioethics in One Health and careers in Global Health. The course combines synchronous and asynchronous activities developed in groups by mixing students from different institutions and countries. Forty-four experts from 22 institutions of the Americas, Africa, Europe, and Asia collaborated with the course content. Some challenges to implementing the course were the different criteria to assign credits across institutions, the lack of bibliographic material across all partners, limited overlap hours and periods for synchronous activities, and short semester overlap across institutions. Despite the challenges for implementation, the entire process of planning and delivering the course involves intense in
