Politics of COVID-19 vaccine mandates: Left/right-wing authoritarianism, social dominance orientation, and libertarianism.

Mandatory and punitive vaccination policies, such as requiring vaccination certificates for public activities and firing employees who refuse vaccination, have raised considerable objections. With a sample of U.S. crowdsourced workers ( = 983), this study investigates how four ideologies-left-wing authoritarianism (LWA), right-wing authoritarianism (RWA), social dominance orientation (SDO), and libertarianism-explain vaccine acceptance and attitudes toward vaccine policies. Results show that LWA predicts higher vaccine acceptance and support for COVID-19 vaccine mandates and the punishment of unvaccinated individuals, whereas libertarianism and RWA show negative relationships. SDO is linked to opposition to vaccine mandates. This study underscores the role of specific ideological components in shaping attitudes toward vaccine policies while also contributing to the arguments that LWA and libertarianism have important implications for studying sociopolitical attitudes.
