Objective: To evaluate the effectiveness of a vaccination education module to improve vaccine expectations and behaviors among college freshmen. Participants: The participants were 177 college freshmen at one private Utah university. Participants were eligible for this study if admitted as new freshmen during the 2019-2020 school year. Methods: The study was a cross-sectional pre- and post-education evaluation assessing vaccine expectations and behaviors using Likert-type and open-ended questions. Results: After completing the vaccination education module, participants' vaccine expectations and behavioral intentions improved. Participants reported they were more likely to be up-to-date on personal vaccines and more likely to expect other students to be up-to-date on their vaccinations. Participants were more likely to ask other students to vaccinate and were also more likely to ask their family members to be vaccinated. Conclusions: This online vaccination education module effectively improved participants' vaccine expectations and behavioral intentions.
