Tue, 06/01/2021 LAWRENCE — In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how to communicate about vaccine efficacy during health crises. In the runup to the 2020 election, then-president Donald Trump claimed a COVID-19 vaccine could be ready before people went to the polls. About that time, millions were flocking to Parler, a new social media platform that promised a free speech environment via unregulated posts. A trio of KU doctoral students in journalism & mass communications analyzed a sample of 400 posts on the platform between November 2020 and January 2021 about the vaccines. Results showed people followed messages of conservative political leaders, shared misinformation and reinforced messages shedding doubt on vaccine efficacy.
