During the early phase of the epidemic, the team had reported the high levels of perceived risk and mild anxiety of Hong Kong general population. In this 5-round longitudinal online survey, they included vaccine-related questions to track the major psychobehavioural responses of Hong Kong people over time and examine the determinants of their intentions to receive COVID-19 vaccine. The result showed that perceived pandemic severity had decreased but perceived self-susceptibility remained high among Hong Kong population. Moreover, greater anxiety, confidence in vaccine, collective responsibility and weaker complacency were associated with higher tendency to receive vaccines.
