This cross-sectional study was conducted in September 2021 among 1,045 Bangladeshi older adults aged 60 years or above to explore the COVID-19 vaccination coverage and its associated factors. We used a semi-structured questionnaire to collect data on participants' sociodemographic and lifestyle characteristics, and COVID-19 related information (selected based on an extensive literature review). A multinomial logistic regression model was used to identify the factors independently associated with vaccine receipt. Nearly, two-thirds of the participants (64.5%) were unvaccinated and 12.5% received a single dose. Among the unvaccinated, approximately 94% reported that there was a problem in accessing the vaccine. We found that participants with formal schooling had 42% lower risk of being unvaccinated (RRR (Relative Risk Ratio) = 0.58, 95% CI 0.42-0.80) or 39% lower risk of receiving a single dose (RRR = 0.61, 95% CI 0.39-0.96) than the participants having no formal schooling. The middle family monthly income groups had 65% higher risk (RRR = 1.65, 95% CI 1.17-2.32) and rural participants had 84% higher risk (RRR = 1.84, 95% CI 1.26-2.70) of not receiving vaccines compared to their counterparts. Also, the participants with non-communicable chronic conditions had a significantly lower risk of being unvaccinated (RRR = 0.49, 95% CI 0.35-0.68) or receiving a single dose (RRR = 0.49, 95% CI 0.31-0.77) compared to their counterparts. This finding may help strengthen the existing efforts to maximize vaccine coverage among older populations in Bangladesh and reach herd immunity to break the transmission chain and gain greater overall population protection more rapidly.
本横断面研究于 2021 年 9 月在孟加拉国 1045 名 60 岁及以上的老年人中进行，旨在探讨 COVID-19 疫苗接种覆盖率及其相关因素。我们使用半结构式问卷收集参与者的社会人口统计学和生活方式特征以及 COVID-19 相关信息（根据广泛的文献回顾选择）。使用多变量逻辑回归模型确定与疫苗接种相关的独立因素。近三分之二的参与者（64.5%）未接种疫苗，12.5%接种了一剂。在未接种疫苗的人群中，约 94%的人报告在接种疫苗方面存在问题。我们发现，接受正规教育的参与者未接种疫苗的风险降低了 42%（RRR（相对风险比）= 0.58，95%CI 0.42-0.80）或接种一剂的风险降低了 39%（RRR= 0.61，95%CI 0.39-0.96）比没有接受正规教育的参与者。中等家庭月收入群体未接种疫苗的风险增加了 65%（RRR= 1.65，95%CI 1.17-2.32），农村参与者未接种疫苗的风险增加了 84%（RRR= 1.84，95%CI 1.26-2.70）与各自的对照组相比。此外，患有非传染性慢性疾病的参与者未接种疫苗的风险显著降低（RRR= 0.49，95%CI 0.35-0.68）或接种一剂的风险降低（RRR= 0.49，95%CI 0.31-0.77）与各自的对照组相比。这一发现可能有助于加强孟加拉国老年人群体现有努力，最大限度地提高疫苗接种覆盖率，实现群体免疫，打破传播链，更快地获得更广泛的人群保护。
