Mapping Adult Vaccine Confidence in Future Health Professionals: A Pilot Study among Undergraduate Students at Two Universities in Greece.

Health professionals' recommendations increase vaccine uptake. We aimed to document stances, practices regarding adult vaccination, and their predictors among undergraduate medical and biomedical science students, as well as their perspectives on increasing vaccine confidence. Among the 430 participants, third-year students from two universities in Greece, only 25.4% were in favor of all vaccines, while no refuters were detected. Predictors of recommending vaccination were the Attitudes Towards Adult Vaccination (ATAVAC) Value (OR 3.26, < 0.001) and ATAVAC Safety subscales scores (OR 1.36, < 0.05), being a medical student (OR 2.45, < 0.05), and having better self-rated health status (OR 2.27, < 0.05). The importance of getting vaccinated as health professionals was recognized by participants with a higher ATAVAC value (OR 5.39, < 0.001), ATAVAC Safety scores (OR 1.46, < 0.05), and increased knowledge regarding the National Immunization Program (OR 1.31, < 0.05). The God Locus of Health Control (GLHC) was a predictor only in vaccination against COVID-19 (OR 0.91, < 0.05). Improving community health literacy and health providers' education, boosting trust in authorities, and adopting a person-centered approach emerged as the main themes regarding how to increase vaccine confidence. Mapping health professionals' confidence in vaccines and providing lifelong training support is pivotal in supporting positive attitudes, enhancing their competence, and promoting vaccination in the post-COVID-19 era.
