Using "pop-up" clinics and live-attenuated influenza vaccine to reduce barriers to flu vaccination among college students

Background: College students have cited inconvenience, ease of forgetting, and lack of time as barriers to influenza (flu) vaccine receipt. We hypothesized that "pop-up" clinics and live-attenuated influenza vaccine (LAIV) would facilitate delivery and align with preferences of college students. Methods: During the 2023-2024 flu season, undergraduate participants were recruited to receive LAIV at 5 "pop-up" clinics across a large midwestern campus. Individuals who received LAIV were approached to complete a Likert-scale survey asking about their experience. Results: Across all clinics, 337 individuals received LAIV and 129 completed the survey. Respondents reported that "pop-up" clinics decreased barriers to vaccination. Regarding LAIV acceptance, 44.2% noted a preference for LAIV while 46.5% noted no preference between intranasal and injectable vaccines. Importantly, over 27% of students stated they would not have received vaccine without this "pop-up" clinic option. Conclusion(s): "Pop-up" clinics and LAIV effectively alleviate barriers to facilitate flu vaccination for college students.
