A COVID-19 vaccine booster dose is effective and safe for older adults. This study investigated facilitators and barriers to take up a COVID-19 vaccine booster dose among older adults in Hong Kong. Participants were Chinese-speaking community-dwelling adults aged ≥65 years. Telephone numbers were randomly selected from up-to-date telephone directories. A total of 395 participants completed the telephone interview. Logistic regression models were fitted. Among the participants, 31.6% received a COVID-19 vaccine booster dose. After adjustment for significant background characteristics, positive attitudes toward the booster dose, perceiving significant others would support them to receive the booster dose, and less uncertainty regarding the choice of the booster dose was associated with higher uptake of a COVID-19 vaccine booster dose. Concerns about poorer responses to the booster dose due to older age and the presence of chronic conditions were negatively associated with the dependent variable. In addition, the belief that governmental promotional materials could address their concern and were helpful for them to make decisions was associated with a higher COVID-19 vaccine booster dose uptake. Improving booster dose health promotion materials, modifying perceptions, involving significant others and reducing uncertainty are potentially useful strategies to improve COVID-19 vaccine booster dose uptake among older adults.
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新冠病毒疫苗加强针的促进因素和障碍。参与者为年龄≥65岁、讲中文的社区居住成年人。电话号码从最新的电话簿中随机抽取。共有395名参与者完成了电话访谈，并拟合了逻辑回归模型。在参与者中，31.6%接种了新冠病毒疫苗加强针。在对显著的背景特征进行调整后，对加强针的积极态度、认为重要他人会支持他们接种加强针以及对加强针选择的不确定性较低与更高的新冠病毒疫苗加强针接种率相关。因年龄较大和患有慢性病而对加强针反应较差的担忧与因变量呈负相关。此外，认为政府宣传材料可以解决他们的担忧并有助于他们做出决策的信念与更高的新冠病毒疫苗加强针接种率相关。改进加强针健康促进材料、改变观念、让重要他人参与以及减少不确定性是提高老年人新冠病毒疫苗加强针接种率的潜在有用策略。
