Negative consequences of failing to communicate uncertainties during a pandemic: an online randomised controlled trial on COVID-19 vaccines

Year: 2022

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: OBJECTIVE: To examine the impact of the government communicating uncertainties relating to COVID-19 vaccine effectiveness on vaccination intention and trust after people are exposed to conflicting information. DESIGN: Experimental design where participants were randomly allocated to one of two groups. SETTING: Online. PARTICIPANTS: 328 adults from a UK research panel. INTERVENTION: Participants received either certain or uncertain communications from a government representative about COVID-19 vaccine effectiveness, before receiving conflicting information about effectiveness. MAIN OUTCOME MEASURES: Vaccination intention and trust in government. RESULTS: 0.34, 95% CI (0.12 to 0.56), p=0.002) after receiving conflicting information. CONCLUSIONS: Communicating with certainty about COVID-19 vaccines reduces vaccination intention and trust if conflicting information arises, whereas communicating uncertainties can protect people from the negative impact of exposure to conflicting information. There are likely to be other factors affecting vaccine intentions, which we do not account for in this study. TRIAL REGISTRATION NUMBER: Open Science Framework: https://osf.io/c73px/.
