This study examines the factors influencing COVID-19 vaccination intentions among Chinese residents over the age of 60, with a focus on the mediating roles of Health Beliefs and Cues to Vaccination Action in the relationship between vaccine knowledge and vaccination intentions. We conducted a cross-sectional online survey involving 1,305 participants from Southwest China. Multiple logistic regression analysis identified potential determinants of vaccination intention, including socioeconomic characteristics, knowledge, health beliefs, and cues to vaccination action. Furthermore, mediation analysis using the causal mediation analysis method explored the mediating effects within the knowledge-to-intention pathway. Vaccination intention and its related factors: among the 1212 elderly people included in the study, 92.9% expressed willingness to receive the COVID-19 vaccine. Main factors influencing their vaccination willingness included Residency (urban vs. rural, OR = 0.47, p < 0.01), Age (75 + vs. others, OR = 0.41, p < 0.05), Marital status (OR = 0.36, p < 0.01), Occupation ( business/service vs. others, OR = 0.33, p < 0.05), Awareness of vaccine effectiveness (OR = 1.23, p < 0.01), Cues to vaccination action (OR = 1.31, p < 0.01) and COVID-19 related knowledge (OR = 1.06, p < 0.01). The analysis revealed two significant mediators-Health Beliefs and Cues to Vaccination Action. These mediators (p<0.05 for both natural indirect effect and natural direct effect) acted along two key pathways: (1) From Knowledge of COVID-19 to Health Beliefs to Vaccination Intention: Natural Direct Effects (NDE) ranged from 0.012 to 0.016, with Natural Indirect Effects (NIE) from 0.001 to 0.003, indicating that mediators accounted for 4% to 18% of the total effect. (2) From Knowledge of COVID-19 to Cues of Vaccination Action to Vaccination Intention: NDE ranged from 0.012 to 0.016 and NIE from 0.002 to 0.003, with mediators accounting for 9% to 20% of the effect. The intention to vaccinate against COVID-19 among older adults varies significantly based on socioeconomic and health belief factors. The study identifies health beliefs and cues to action not only as direct contributors but also as crucial mediators in the pathway from knowledge to vaccination intention among older individuals. These findings can extend our understanding of the impact of sociodemographic factors and health beliefs on the COVID-19 vaccination willingness among older adults.
