Intention to vaccinate young children against COVID-19: A large-scale survey of Hong Kong parents.

ABSTRACT

COVID-19 vaccines (Sinovac and Pfizer/BioNTech) have recently been approved for Hong Kong children. Understanding parental intentions to vaccinate children against COVID-19 is important to the development of an effective COVID-19 vaccine campaign. From a large-scale, geographically representative dataset in Hong Kong (N = 11,141), we examined parents' intentions to vaccinate their children against COVID-19 under three conditions (1) no policy restrictions, (2) vaccination rate considered for school resumption, and (3) more choices of vaccine. Results showed that levels of vaccine hesitancy in Hong Kong parents are high. Hong Kong parents' intention to vaccinate their children was highest when there were more vaccines to choose from, followed by when vaccination rate was considered to resume school, and when there was no policy restrictions. Finally, Hong Kong parents with higher education backgrounds and family income were less willing to vaccinate their children. Together, these findings indicate that effective vaccines campaign should consider the characteristics and preferences of parents who have little intention to vaccinate within a specific social context.
