COVID-19 booster vaccine attitudes and behaviors among university students and staff: the USC Trojan Pandemic Research Initiative

ABSTRACT

IntroductionAlthough COVID-19 vaccines significantly reduce morbidity and mortality, recent evidence suggests that immunity wanes after 6-9 months, and that a third vaccine dose could further reduce COVID-19 transmission and severe illness. However, previous studies have not assessed attitudes about getting booster doses. This study examined COVID-19 booster vaccine attitudes and behaviors among university students and staff in the fall of 2021. MethodsParticipants responded to an email invitation and completed electronic surveys. Results. In our sample, 96.2% of respondents indicated willingness to get a COVID-19 booster shot at least once per year. In both bivariate and multivariate analyses higher trust in science was associated with having higher odds of booster willingness. Those who identify as Black, on average, reported trusting science less than other racial/ethnic groups. ConclusionsOur findings demonstrate high willingness to receive a COVID-19 booster shot and highlight the importance of educational and motivational messages that focus on trust in science to increase willingness to get the COVID-19 booster. More research is needed to better understand the impact of cultural beliefs on booster willingness and vaccine hesitancy. This understanding will help determine what messages and populations to target to increase booster willingness in the future.
