Concurrently, the proliferation of digital health information has raised concerns about the negative effects of information overload and cyberchondria. However, the psychological pathways linking these digital phenomena to vaccine hesitancy, particularly for older adults, remain underexplored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>This study aims to examine the association between health information overload on excessive online search (cyberchondria) and influenza vaccine hesitancy among Chinese older internet users.
