The Health Belief Model (HBM) has been widely studied, but it is unclear how social media post creators use HBM constructs to influence the public’s awareness of health topics, particularly for COVID-19 preventative health behaviors. Moreover, there is limited knowledge about how content creators enhance user engagement with COVID-19 vaccine tweets. A content analysis of COVID-19 vaccine tweets (n = 362) examined how HBM constructs were used in social media posts and their relationship to content creator characteristics (e. g., race, education level) and user engagement behaviors (e. g., number of favorites). Content creators’ tweets about COVID-19-related topics generally centered on two HBM constructs-benefits and barriers-while fewer tweets emphasized perceived susceptibility or self-efficacy; tweets containing these constructs were retweeted less often. Findings revealed that tweets from politicians, health experts, and white and Asian sources emphasized the perceived benefits of the COVID-19 vaccine. Individual tweets, especially from Black individuals and celebrities, generated more user engagement. Understanding the factors that contribute to social media user engagement with health-related content is important for designing more focused and impactful health communication campaigns and promoting healthier habits and perspectives. Thus, by demonstrating the possible relevance of the HBM to digital communication strategies or health campaigns, our study provides useful guidance for health promoters and policymakers who use social media to raise public health awareness.
