A second COVID-19 vaccine booster dose is effective and safe for older adults. This study investigated hesitancy to take up a second COVID-19 vaccine booster dose and its determinants among older adults in Hong Kong. Participants were Chinese-speaking community-dwelling adults aged 65 years or above. Telephone numbers were randomly selected from up-to-date telephone directories. A total of 370 participants completed the telephone survey. Logistic regression models were fitted for data analysis. Among the participants, half (52.4%) were hesitant to receive the second COVID-19 vaccine booster dose. After adjustment for significant background characteristics, perceived benefits (AOR: 0.50, 95%CI: 0.42, 0.60), cues to action (AOR: 0.39, 95%CI: 0.30, 0.52), and perceived self-efficacy (AOR: 0.37, 95%CI: 0.21, 0.66) of receiving the second booster dose were associated with lower vaccine hesitancy. Perceived barriers (AOR: 1.23, 95%CI: 1.12, 1.34) and vaccine fatigue (tired of receiving repeated COVID-19 vaccination) (AOR: 1.90, 95%CI: 1.52, 2.38) were associated with higher vaccine hesitancy. Level of hesitancy to receive the second booster dose was high among older adults in Hong Kong. Health authorities should address vaccine fatigue and modify perceptions related to the second booster dose.
第二剂新冠病毒疫苗加强针对于老年人是有效且安全的。本研究调查了香港老年人接种第二剂新冠病毒疫苗加强针的犹豫情况及其决定因素。参与者为65岁及以上说中文的社区居住成年人。电话号码是从最新的电话簿中随机抽取的。共有370名参与者完成了电话调查。采用逻辑回归模型进行数据分析。在参与者中，一半（52.4%）对接种第二剂新冠病毒疫苗加强针持犹豫态度。在对显著的背景特征进行调整后，对接受第二剂加强针的感知益处（比值比：0.50，95%置信区间：0.42，0.60）、行动提示（比值比：0.39，95%置信区间：0.30，0.52）以及感知自我效能（比值比：0.37，95%置信区间：0.21，0.66）与较低的疫苗犹豫相关。感知障碍（比值比：1.23，95%置信区间：1.12，1.34）和疫苗疲劳（厌倦重复接种新冠病毒疫苗）（比值比：1.90，95%置信区间：1.52，2.38）与较高的疫苗犹豫相关。香港老年人对接种第二剂加强针的犹豫程度较高。卫生当局应解决疫苗疲劳问题，并改变与第二剂加强针相关的观念。
