The purpose of this study is to seek an effective strategy to promote COVID-19 vaccination among young adults. Given that COVID-19 is less deadly for young adults, this study explores whether highlighting potential benefits or disadvantages that others may experience as a result of one's vaccination increases young adults' intention to get vaccinated, particularly for those who have low perceived risk of COVID-19. To test this idea, we conducted an experiment and analyzed the effect of interaction between message frame (gain vs. loss) and reference point (self vs. others) on intention for vaccination by one's perceived risk (low vs. high). The results show that for those with low perceived risk of COVID-19, messages about potential negative consequences to others (e.g., family, friends, community members) from one's failure to get vaccinated led to message elaboration and favorable attitude toward vaccination, which in turn promoted one's intention to get vaccinated. We discuss practical implications of the findings for message strategies that target populations experiencing COVID-19 disparities.
