This study examined the joint effects of information format and emotions on intention to receive and attitude towards COVID-19 vaccination. Experiment 1 showed that both narrative and non-narrative information enhanced vaccination intention and attitude, regardless of whether participants were in a neutral, happy, or angry state. Experiment 2, in which richer information was used, showed that, regardless of emotional state, both narrative and non-narrative information enhanced intention to receive vaccination; narrative information enhanced attitude towards vaccination, but non-narrative information did not have a significant effect. This study suggests that both narrative and non-narrative information can be effective in increasing the intention to receive COVID-19 vaccination, independent of individuals' emotional state. However, it may be more advantageous to employ richer narrative information to bolster the attitude towards COVID-19 vaccination.
