Improving communication of COVID-19 vaccination benefits and harms: Effects of Fact Boxes and Bubble Diagrams on Perception and Intent to Recommend COVID-19 Vaccination
SessionPoster Session 1
DescriptionSince various risk information about COVID-19 vaccination has been provided, interpretation of the information is controversial among the public. The present research examined whether and how risk information using visual aids influenced the perceived benefits and harms of COVID-19 vaccine, as well as the intention to recommend the vaccine depending on age (30-, 50-, and 70-year-old adults). Participants (N= 2000) were randomly assigned to a particular condition (control vs. fact boxes vs. fact boxes and bubble diagrams) and asked to rate their perceptions and intention to recommend the vaccine. The results showed that visual aids influenced the intention to recommend for 30- and 50-year-old adults. The effects of the visual aids were different depending on the numeracy; higher-numeracy group perceived the vaccine more effective, less harms, and more intent to recommend the vaccine than lower-numeracy group. Implications for use of visual aids and consideration of the demographic variables are discussed.
