China started to offer a booster dose of COVID-19 vaccine to members of the adult population in October 2021. This study investigated the behavioral intention to receive a booster dose of COVID-19 vaccine among factory workers who had completed their primary vaccination series. Participants were full-time factory employees at least 18 years of age in Shenzhen, China. In Shenzhen, factory workers need to receive a physical examination every year. The study sites covered all six organizations providing physical examinations for factory workers. All eligible workers attending these sites between 26 and 31 October 2021 were invited to complete an online survey. This study was based on 2329 participants who had completed the primary COVID-19 vaccination series. Two-level logistic regression models were fitted. Among the participants, 84% intended to receive a free booster dose of COVID-19 vaccine within the next six months. After controlling for significant background characteristics, we found that perceptions related to a booster dose as well as interpersonal level factors such as information exposure on social media, thoughtful consideration of the veracity of the information, and satisfaction with vaccine-related promotional materials were determinants of behavioral intention. Factory workers in China reported a high level of behavioral intention to receive a booster dose of the COVID-19 vaccine.
中国于 2021 年 10 月开始为成年人群提供 COVID-19 疫苗加强针。本研究调查了已完成基础免疫系列接种的工厂工人对 COVID-19 疫苗加强针的接种意愿。参与者为中国深圳的全职工厂员工，年龄至少 18 岁。在深圳，工厂工人每年都需要进行体检。研究地点覆盖了为工厂工人提供体检的所有 6 个组织。所有符合条件的工人于 2021 年 10 月 26 日至 31 日期间在这些地点参加体检时，均被邀请完成在线调查。本研究基于 2329 名已完成基础 COVID-19 疫苗接种系列的参与者。拟合了两水平逻辑回归模型。在参与者中，84%的人打算在未来六个月内免费接种 COVID-19 疫苗加强针。在控制了显著的背景特征后，我们发现，与加强针相关的认知以及社交媒体上的信息暴露、对信息真实性的深思熟虑、对疫苗相关宣传材料的满意度等人际层面因素是行为意愿的决定因素。中国的工厂工人报告称，他们对接种 COVID-19 疫苗加强针的意愿很高。
