Abstract

Objective: To analyze the level of knowledge about hepatitis B and vaccination coverage among first-year medical students. Methods: This is a cross-sectional, descriptive, and quantitative study conducted with 162 students from a private university in Fortaleza, Ceará, Brazil. The sample was obtained by convenience. Data were collected through a structured questionnaire developed by the authors, including questions on knowledge and vaccination status. Data was analyzed using descriptive statistics. The study was approved by the Research Ethics Committee (approval number 6,689,258). Results: Students demonstrated adequate knowledge of basic aspects of the disease; however, important gaps were identified regarding transmission routes and preventive measures. Vaccination was widely recognized, but fewer than half of the students had completed the full vaccination schedule. There was low adherence to anti-HBs serological testing and a discrepancy between perceived protection and actual immunological status. Conclusion: Students present significant gaps in applied knowledge and immunization against hepatitis B, highlighting the need for early and continuous educational strategies in medical training.
