Analysis of public opinion polls about COVID-19 vaccines: Theoretical and policy implications for vaccine communication and campaigns to address vaccine hesitancy

Abstract

This study analyzed 1432 questions asked in 19 surveys (N = 43,014) on COVID-19 vaccines between January 2020 and August 2022 using dimensions including (1) information sources about COVID-19 vaccine, (2) information about the access, effectiveness, and side effects of COVID-19 vaccine, (3) COVID-19 vaccine hesitancy (i.e. false perception, skepticism, and vaccine refusal), (4) motivations to get the COVID-19 vaccine (i.e. to perform routine activities, convenience, incentives, influences, and travel requirement), (5) false perceptions caused vaccine refusal, and (6) intentions to get vaccinated. Our results show that vaccine refusal was rampant throughout the pandemic and mostly attributed to the rush in the vaccine development process and perceived safety risks. Additionally, our analysis indicates that people’s motivation to get vaccinated came from varied sources such as doctors, family members, and politicians. Lastly, mandating vaccines during the pandemic did not significantly increase uptake among individuals who were initially skeptical, and concerns about the rapid development of the vaccine were a major cause of vaccine hesitancy. Findings were discussed and interpreted using the information deficit model, the two-step flow theory, and the reactance theory. This research provides valuable insights and practical implications, along with significant theoretical contributions and policy recommendations.
