University students' knowledge, perceptions, and sources of information on routinely recommended vaccines.

To evaluate university students' perceptions of the importance of routine vaccines, knowledge of vaccines, most trusted sources of vaccine information, and interest in learning more about vaccines. 2,223 students attending four universities across Pennsylvania. A 32-question electronic survey was administered to university students between March and May 2023. Survey topics included importance of vaccines, self-rated knowledge of vaccines, sources of vaccine information, and interest in learning more about vaccines, including how they work, and safety concerns. Most responding students perceived vaccination as important, but this varied by major, vaccination status, and living situation. About 30% of students did not know where to find vaccine information on campus. Over 30% of students, especially non-white and international students, were interested in learning more. Students need and desire more effective vaccine education. Educational interventions should provide outreach tailored to different groups of students and focus on visual instructional tools, such as videos and brochures, from trusted sources like healthcare providers.
