This article proposes a definition of the field of Health and Biomedical Informatics, in line with recent international developments. According to the authors, there are several myths or misconception concerning the future development of this scientific and professional discipline. We describe the current situation of Health and Biomedical Informatics at an international level, include specific analysis for the two countries where the authors have worked (Spain and Australia) and finally propose a series of recommendations to improve it. All this analysis is carried out in three areas: education, research, and professionalism (characterisation and development of the profession). Defining the body of knowledge of the discipline itself is an initial step that must be made and taken as soon as possible.
