Impact assessment of an educational course on vaccinations in a population of medical students

BACKGROUND: The inadequate knowledge about vaccinations of healthcare workers, including medical doctors, has certainly contributed to the spread of the vaccine hesitancy. Therefore, it is essential to improve the level of knowledge of future doctors. The aim of the study is to evaluate the impact of a course about vaccinations on the knowledge of medical students. METHODS: Medical students were asked to complete an anonymous questionnaire before and after a seminar on vaccination that they willingly attended. The two questionnaires contained the same 10 questions about vaccines. Only the students who had attended the lecture were allowed to fulfil the post-lecture questionnaires through the learning management system (LMS) called “Moodle”. A descriptive statistical analysis of the data collected through the comparative evaluation of the answers before and after the seminar was performed. Mann-Whitney test for two independent samples was used to compare medians score before and after the interventions. RESULTS: A total of 100 medical students filled the pre-lecture questionnaire and 81 of them completed the post-lecture questionnaire. Knowledge of the students on the indication of the MMR (Measles-Mumps-Rubella) vaccine strongly improved after the seminar. Moreover, the number of students who would recommend vaccination for pertussis and influenza during pregnancy increased significantly by 37% and 19% respectively after the seminar and those aware of the need for Herpes Zoster vaccination over the age of 65 increased by 22%. DISCUSSION: For future doctors, a thorough knowledge about vaccinations is increasingly required in order to deal with vaccine hesitancy. Extracurricular seminars about vaccines, provided in the second half of the course of study, can have a highly positive impact.
