Neighborhood social cohesion is associated with the willingness toward the booster dose of COVID-19 vaccines among the Chinese older population

Neighborhood social cohesion is a prominent psychosocial factor during the pandemic, and trust in neighbors is critical for implementing health prevention-related behaviors with public health messages. We planned to specifically explore the association between neighborhood social cohesion and vaccine acceptability among older adults (≥60 years) in China. Using a random stratified sampling method, an anonymous cross-sectional online survey was conducted in mainland China via a professional scientific data platform from May 25 to June 8, 2022. A revised Social Cohesion Scale was applied to evaluate the level of neighborhood social cohesion. Of the 3,321 recruited respondents aged 60 and above, 82.8% (95% CI: 81.5–84.1) reported their willingness to be vaccinated. With all significant covariates adjusted, older adults with moderate (aOR = 1.77, 95% CI: 1.04–3.04) and high level of social cohesion (aOR = 2.21, 95% CI: 1.29–3.77) were more likely to receive the booster dose. Our findings remained robust in a series of models after controlling for different covariates. Uncertainty about contraindications (38.3%), underestimation of their vulnerability (33.1%), and concerns about vaccine safety (32.0%) were the three main reasons for vaccine hesitancy. Therefore, building a harmonious community environment, strengthening neighborhood communication and exchange, and making good use of peer education among neighbors may become a breakthrough to promote herd immunity, especially for vulnerable older adults with limited social networks.
