[Objective] This paper tries to identify the opinion leaders of Weibo and examines their roles in information dissemination. [Methods] We adopted, a method of two-step clustering to identify opinion leaders of the “illegal vaccine” event. Then, we created a network matrix for these opinion leaders based on their relationship. Finally, we analyzed the sentiments of the Weibo users to evaluate the role of opinion leaders’ network. [Results] The overall users’ sentiments was negative. The opinion leaders’ network posed significant impacts on the sentiments of average users. [Limitations] Only examined our method with one event. [Conclusions] The celebrities and opinion leaders play important role to sway the public opinion online.
