Information Consumption, Trust Dynamics and COVID-19 Vaccine Hesitancy among Older Adults: Implications for Health Messaging

Staying well informed about the evolving COVID-19 pandemic and vaccine recommendations is vital for older adults, especially for low-income older adults, who have been disproportionately impacted by the pandemic. However, the overwhelming infodemic poses a significant challenge, affecting vaccine decision-making. This study explores how a group of predominantly low-income older adults navigate health information and how their trust in information and vaccines evolves throughout the pandemic. Our objective is to provide insights that will guide future public health messaging for this demographic. Analyzing qualitative data from 77 older adults (aged 65 to 94) collected through focus groups and interviews, our findings reveal that participants’ experiences with information overload eroded their trust in authority, leading to vaccine hesitancy. Moreover, the need for a booster has affected belief in vaccine safety and efficacy. As participants lost faith in the media and authoritative sources, they increasingly leaned on personal networks for guidance. These results underscore the urgent necessity for clear, unambiguous ongoing vaccine guidance to restore institutional trust among older adults. Additionally, recognizing the influential role of direct networks in vaccine decisions, integrating care workers, service providers, and peer-to-peer support into health messaging mechanisms could prove valuable.
