近年来以微博、微信为代表的社交媒体的广泛应用改变了风险事件的建构格局。了解风险事件发生后公众对政府及主流媒体传播信息的回应逻辑及风险传播参与有助于改善风险传播现状。考虑到我国风险的特殊性及传播具有的民主属性,本研究以2018年问题疫苗事件的615篇新闻与1434条跟帖为样本进行内容分析。研究发现,虽然公众接受官方科学话语,对疫苗风险有着广泛的正确认知,但他们担心风险事件再次发生,放大风险存在的概率。主要原因在于主流媒体面对突发风险事件,仍没完成从“传达者”到“沟通者”的转型,其巨大影响力限制了社交媒体舆论场话语的多元性,单一的风险建构方式增加了公众的疑虑和不确定,社会化媒体还有待真正发展成为弥合风险传播双方鸿沟的利器。
