Abstract

Background: Low vaccination coverage among travelers poses a critical challenge to global health security. Indeed, public concerns regarding vaccines can lead to vaccine reluctance and refusal, but evidence about the impacts of concerns regarding vaccines on the uptake of travel vaccinations remains sparse. We examined the associations between concerns about vaccines and vaccination behavior among travelers.

Methods: Japanese travelers aged 18 years or older, who stayed at a guesthouse in New Delhi, India, were targeted (n = 153). We conducted cross-sectional surveys from August 23 to September 2, 2019, and from February 19 to March 5, 2020. We examined the associations of three concerns regarding vaccines (5-point scale)-serious side effects from vaccines, vaccine safety, and vaccine effectiveness-with the uptake of travel vaccinations.

Results: In total, 60 participants (39.2 %) had been vaccinated for this or a past trip. After adjusting for all potential confounding variables, concerns about serious side effects from vaccines and vaccine safety were negatively associated with the uptake of travel vaccinations. The ORs (95 % CIs) for 1-point increases in concerns about serious side effects from vaccines and vaccine safety were 0.72 (0.52, 0.99) and 0.71 (0.52, 0.96), respectively. Sensitivity analyses did not change the results substantially.

Conclusions: Concerns about vaccine safety issues were negatively associated with the uptake of travel vaccinations among the participants, with no corresponding association observed for vaccine effectiveness. Addressing concerns about vaccine safety issues, rather than vaccine effectiveness may contribute to an increased uptake of travel vaccinations.

前往印度的日本经济型旅行者对疫苗和接种行为的担忧。
背景:旅行者中疫苗接种覆盖率低对全球健康安全构成了严峻挑战。事实上,公众对疫苗的担忧会导致不愿接种和拒绝接种疫苗,但有关疫苗担忧对旅行接种率影响的证据仍然很少。我们研究了旅行者对疫苗的担忧与疫苗接种行为之间的关联:方法:我们以在印度新德里一家宾馆住宿的 18 岁或以上的日本旅行者为对象(n=153)。我们于 2019 年 8 月 23 日至 9 月 2 日和 2020 年 2 月 19 日至 3 月 5 日进行了横断面调查。我们研究了对疫苗的三种担忧(5 分制)--疫苗的严重副作用、疫苗的安全性和疫苗的有效性--与旅行疫苗接种率的关系:共有 60 名参与者(39.2%)在这次或过去的旅行中接种过疫苗。在对所有潜在混杂变量进行调整后,对疫苗严重副作用和疫苗安全性的担忧与旅行疫苗接种率呈负相关。对疫苗严重副作用和疫苗安全性的担忧增加 1 个百分点的 ORs(95% 置信区间)分别为 0.72 (0.52, 0.99) 和 0.71 (0.52, 0.96)。敏感性分析没有使结果发生重大变化:结论:对疫苗安全问题的担忧与参与者接种旅行疫苗的比例呈负相关,而对疫苗有效性的担忧与接种比例无相应关系。解决对疫苗安全性问题的担忧而非疫苗有效性问题可能有助于提高旅行疫苗的接种率。
