Message Mapping as a Tool for Public Health Emergency Risk Communication: Social Media-Related Considerations
This in-person lecture is presented by the Institute for Pandemics ((IfP) at the University of Toronto.
The Institute for Pandemics welcomes Professor Daniel Barnett on June 5, 2025, to present a lecture on his work on public health emergencies.
In the face of a widening array of threats to population health, research on public health agencies’ leveraging of social media for public health emergency risk messaging has critical and timely relevance. In this presentation, entitled Message Mapping as a Tool for Public Health Emergency Risk Communication: Social Media-Related Considerations, Dr. Daniel Barnett from Johns Hopkins Bloomberg School of Public Health will present findings from his team’s research to map dissemination and viewers' consumption of YouTube videos on COVID-19 vaccination health messaging. The results are highly applicable to public health emergency risk communicators who seek to better understand the platform mechanisms that determine the spread of videos and measures of viewer reactions based on viewer sentiment.
