Using a 10 week nationwide online survey performed during a time period containing the time ahead, the start, and the peak of a COVID-19 outbreak in Taiwan, we investigated aspects that could affect participants' vaccination intentions.
From March to May 2021, we surveyed 1,773 people in Taiwan, aged from 20 to 75 years, to determine potential acceptance rates and factors influencing the acceptance of a COVID-19 vaccine. We used an ordinal logistic regression with a backward selection method to identify factors that affected vaccination intention.
Several factors could increase individuals' vaccination intentions including: being male, older, with an openness personality, having a better quality of life in the physical health domain, having better knowledge and personal health behavior, having more trust in the government, and being worried about misinformation. Perceived risks played a crucial role in the vaccine decision-making process. When the pandemic intensified, people's vaccination intentions increased significantly.
The findings of the present study could highlight individuals' vaccination attitudes and provide governments with an empirical and dynamic base to design tailored strategies to increase vaccination rates.
本研究通过在台湾 COVID-19 爆发期间，开展了一项为期 10 周的全国性在线调查，旨在探讨可能影响参与者疫苗接种意愿的因素。
2021 年 3 月至 5 月，我们对台湾地区 20 至 75 岁的 1773 人进行了调查，以确定 COVID-19 疫苗接种的潜在接受率和影响因素。我们采用有序逻辑回归和向后选择法来确定影响疫苗接种意愿的因素。
多项因素可增加个体的疫苗接种意愿，包括：男性、年龄较大、性格开朗、身体健康领域的生活质量更好、具有更好的知识和个人健康行为、对政府的信任度更高以及对错误信息的担忧。感知风险在疫苗决策过程中起着至关重要的作用。当疫情加剧时，人们的疫苗接种意愿显著增加。
本研究结果可突出个体的疫苗接种态度，并为政府提供设计有针对性策略以提高疫苗接种率的经验和动态基础。
