Abstract

Background

Financial accessibility has emerged as a significant barrier to vaccine uptake following the cessation of universal public funding for coronavirus disease 2019 (COVID-19) vaccination programs. This investigation assessed the intention and determinant factors of COVID-19 vaccination among healthcare workers in Japan in the 2024–2025 pre-season.

Methods

A retrospective survey was conducted utilizing data collected from hospital staff at Okayama University Hospital, Japan, to inform the COVID-19 vaccination strategy in October 2024. The analysis evaluated demographic characteristics, vaccine intention, perceived barriers to vaccination, and maximum acceptable out-of-pocket expenditure.

Results

The study population of 3417 respondents comprised 843 medical doctors (24.7 %), 1131 nurses (33.1 %), 320 other medical staff (9.4 %), 286 dental doctors (8.4 %), and 627 administrative officers (18.3 %). At full cost, 2109 (61.7 %) indicated no intention to receive vaccination, while only 4.4 % expressed willingness to be vaccinated and 33.9 % remained undecided. With total self-payment, the vaccination acceptance rates were the highest and lowest among medical doctors (11.4 %) and nurses (1.0 %), respectively. Cost (38.1 %), followed by safety issues (29.5 %) and concerns regarding efficacy or medical necessity (20.3 %), emerged as the primary barrier. The projected vaccination intention increased to 43.9 % and 54.9 % at reduced self-pay costs of 3000 JPY and 5000 JPY, respectively.

Conclusions

Addressing financial constraints through policy interventions could be effective strategies in increasing overall vaccination coverage among healthcare workers. In addition, providing tailored education on vaccine safety, efficacy, and necessity may further facilitate increased vaccine uptake within this critical population.

2024-2025年日本一所大学医院医护人员COVID-19疫苗接种意向和潜在决定因素

在停止为2019冠状病毒病（COVID-19）疫苗接种计划提供普遍公共资金后，资金可及性已成为疫苗接种的一个重大障碍。本调查评估了2024-2025年日本卫生保健工作者接种COVID-19疫苗的意愿和决定因素。方法利用收集的日本冈山大学医院工作人员数据进行回顾性调查，为2024年10月的COVID-19疫苗接种策略提供信息。该分析评估了人口统计学特征、疫苗意向、疫苗接种的感知障碍和可接受的最大自费支出。结果调查对象3417人，其中医生843人（24.7%），护士1131人（33.1%），其他医务人员320人（9.4%），牙科医生286人（8.4%），行政人员627人（18.3%）。在全额费用下，2109人（61.7%）表示无意接种疫苗，而只有4.4%表示愿意接种疫苗，33.9%仍未决定。在全部自费情况下，疫苗接种率最高的是医生（11.4%），最低的是护士（1.0%）。成本（38.1%），其次是安全问题（29.5%）和对疗效或医疗必要性的担忧（20.3%），成为主要障碍。在减少3000日元和5000日元的自费费用后，预计接种意愿分别增加到43.9%和54.9%。结论通过政策干预解决财政限制可能是提高卫生保健工作者总体疫苗接种覆盖率的有效策略。此外，针对疫苗的安全性、有效性和必要性提供量身定制的教育，可能进一步促进这一关键人群增加疫苗接种。
