COVID-19 vaccination: Examining negative dominance on social media

Vaccine negativity and reluctance didn’t just emerge during the COVID-19 pandemic. In a recent study published in the Disaster Medicine and Public Health Preparedness journal, authors from Loyola University Maryland and Johns Hopkins Bloomberg School of Public Health explored the appearance of negative dominance – a concept in which negative messages outweigh positive, solution-oriented messages in audiences’ perceptions – in the context of COVID-19 vaccine-related information and activity online.

Prior research has looked at media coverage to identify vaccine concerns among the public and its impact on vaccine-related beliefs and behaviors, the spread of misinformation and fake news on the Internet, and the role of social media in aiding vaccine hesitancy, among others. Surprisingly, however, research to date has yet to explicitly explore negative dominance of vaccine-related information online using more recently developed tools for analyzing big data.
