The maternal vaccine coverage rate has been low in Taiwan. We developed an "Influenza Vaccination Reminder Application" and evaluated its efficacy in improving vaccination intention among pregnant women in Taiwan. A randomized controlled trial was conducted to compare the positive change in vaccination intention between the experimental group and the control group. Pregnant women who were more than 20 years old and at less than 32 weeks of gestation were recruited from four regional hospitals in southern Taiwan during November 2020 to April 2021. Pregnant women were randomly assigned to the experimental group, to whom the "Influenza Vaccination Reminder Application" was provided for at least two months, while pregnant women in the control group received regular maternal education only. The differences in knowledge about influenza and its vaccines, attitudes towards maternal influenza vaccination, and behavior intention of influenza vaccination among pregnant women before and after the experiment intervention were compared between two groups. The results included 126 women in the experimental group and 117 women in the control group and showed that the "Influenza Vaccination Reminder Application" increased pregnant women's knowledge about influenza and vaccines (percentage increase in the experimental group and control group: 11.64% vs. 7.39%), strengthened their positive attitudes towards maternal influenza vaccination (percentage increase: 5.39% vs. 1.44%), and promoted positive behavioral intention toward influenza vaccination (proportion of participants with positive change in vaccination intention: 17.46% vs. 7.69%). The study supports use of "Influenza Vaccination Reminder Application" to promote the behavior intention of influenza vaccination among pregnant women in Taiwan.
台湾地区的孕产妇疫苗接种覆盖率一直很低。我们开发了一款“流感疫苗接种提醒应用程序”，并评估了其在提高台湾地区孕妇疫苗接种意愿方面的效果。进行了一项随机对照试验，以比较实验组和对照组在疫苗接种意愿方面的积极变化。2020年11月至2021年4月期间，从台湾南部的四家地区医院招募了年龄超过20岁且孕周小于32周的孕妇。孕妇被随机分配到实验组，为其提供“流感疫苗接种提醒应用程序”至少两个月，而对照组的孕妇仅接受常规的孕产妇教育。比较了两组孕妇在实验干预前后关于流感及其疫苗的知识、对孕产妇流感疫苗接种的态度以及流感疫苗接种的行为意愿的差异。结果包括实验组126名女性和对照组117名女性，结果显示“流感疫苗接种提醒应用程序”增加了孕妇对流感和疫苗的知识（实验组和对照组的百分比增幅：11.64%对7.39%），增强了她们对孕产妇流感疫苗接种的积极态度（百分比增幅：5.39%对1.44%），并促进了流感疫苗接种的积极行为意愿（疫苗接种意愿有积极变化的参与者比例：17.46%对7.69%）。该研究支持使用“流感疫苗接种提醒应用程序”来促进台湾地区孕妇的流感疫苗接种行为意愿。
