Herding behavior in COVID-19 vaccine hesitancy in rural Zimbabwe: The moderating role of health information under heterogeneous household risk perceptions.

COVID-19 vaccine hesitancy poses a global health threat by potentially delaying the attainment of herd immunity to attenuate infection and transmission. Most governments across the world are engrossed with formulating strategies to surmount conservative group behavior such as vaccine hesitancy typical under risky and uncertain situations such as in the case of COVID-19. This paper examines herding behavior in vaccine hesitancy with a special focus on the moderating role of household access to health information from village health workers under different risk perceptions.
