Abstract
Objective: to report the experience of undergraduate nursing students about a health education activity on measles. Experience report: This is an experience report type study developed through the problematization methodology of the Arco de Maguerez, followed by the steps of observing reality, identifying key points, theorizing, hypothesis of solution and returning to reality. The first step was the observation by students of users in the vaccination waiting room at a health unit. The key points came from the students' discussion about people's demand for vaccination and their concerns. Theorizing occurred by searching for scientific evidence in databases, manuals, standards and ordinances. The intervention was an educational health activity on the most important aspects of the disease, especially prevention, with the use of a poster and carrying out fixation activity. Final considerations: the experience provided students with a great reflection on the importance of health education, in addition to the opportunity to have shared knowledge between users and academics about an infectious disease of great relevance in public health, emphasizing the vaccine as the main form of prevention.
