 The study examined parental intentions to vaccinate children against COVID-19 in Hong Kong under three conditions, no policy restrictions, vaccination rate considered for school resumption, and more choices of vaccine. Results showed that levels of vaccine hesitancy are high among Hong Kong parents, with higher education backgrounds and family income being less willing to vaccinate their children. Effective vaccines campaigns should consider the characteristics and preferences of parents who have little intention to vaccinate within a specific social context.
