Abstract

Background

The COVID-19 booster dose (BD) was introduced to enhance protection after the initial vaccination series. However, its acceptance remains low, particularly among healthcare workers (HCWs). This study aimed to assess BD acceptance among HCWs at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, and identify the factors influencing their decision.

Methodology

A cross-sectional study was conducted among 423 HCWs from May to June 2022. Data were collected using a self-administered questionnaire and a convenient sampling technique. Descriptive and inferential analyses were performed using SPSS version 25. Binary logistic regression was applied to identify factors associated with BD acceptance.

Results

A total of 399 HCWs completed the survey, with 51.4 % male, 80.5 % health professionals, and 60.2 % aged 18–30 years. More than half had no prior COVID-19 infection. Despite 86.5 % holding favorable attitudes toward BD, only 28.6 % accepted it. BD acceptance was significantly higher among HCWs aged 31–40 years (AOR = 2.21), 41–50 years (AOR = 4.14), and over 50 years (AOR = 6.00) compared to those aged 18–30 years. Married individuals (AOR = 1.82), those with post-vaccination COVID-19 infection (AOR = 1.94), and those with a favorable attitude toward BD (AOR = 16.74) were more likely to accept it.

Conclusion

Less than one-third of HCWs accepted the COVID-19 BD. Older age, marital status, prior post-vaccination COVID-19 infection, and positive attitudes toward vaccination were significant predictors. Low acceptance among HCWs may influence public confidence in immunization, necessitating targeted interventions to improve uptake.

埃塞俄比亚亚的斯亚贝巴蒂库尔·安贝萨专科医院医护人员对COVID-19疫苗加强剂的接受情况及其影响因素

背景COVID-19加强剂（BD）的引入是为了在初次接种系列疫苗后加强保护。然而，其接受度仍然很低，尤其是在医护人员（HCWs）中。本研究旨在评估埃塞俄比亚亚的斯亚贝巴Tikur Anbessa专科医院医护人员对BD的接受程度，并确定影响他们做出决定的因素。方法 2022年5月至6月，对423名医护人员进行了横断面研究。采用自填式问卷和方便抽样技术收集数据。使用 SPSS 25 版本进行了描述性和推论性分析。结果共有 399 名医护人员完成了调查，其中 51.4% 为男性，80.5% 为卫生专业人员，60.2% 年龄在 18-30 岁之间。超过一半的人之前未感染过 COVID-19。尽管有 86.5% 的人对 BD 持赞成态度，但只有 28.6% 的人接受它。与 18-30 岁的人相比，31-40 岁（AOR = 2.21）、41-50 岁（AOR = 4.14）和 50 岁以上（AOR = 6.00）的医务工作者对 BD 的接受程度明显更高。已婚者（AOR = 1.82）、接种 COVID-19 后感染者（AOR = 1.94）和对 BD 持赞成态度者（AOR = 16.74）更有可能接受 BD。年龄较大、婚姻状况、接种后曾感染 COVID-19 和对接种的积极态度是重要的预测因素。医护人员的低接受度可能会影响公众对免疫接种的信心，因此有必要采取有针对性的干预措施来提高接种率。
