Abstract

Purpose: To investigate the effect of studying abroad on catch-up vaccination coverage for measles, rubella, mumps, varicella, and tetanus during the pretravel consultation among young adult travelers.

Methods: This retrospective cohort study analyzed data from the Japan Pretravel Consultation Registry (J-PRECOR) on individuals aged 18-21 years with childhood vaccination records. Propensity score weighting was used to estimate the average treatment effect on the proportion of participants receiving catch-up vaccination.

Results: Among 1091 eligible participants, the catch-up vaccination need was highest for mumps (65.7 %) and varicella (49.0 %) and lowest for measles (9.9 %) and rubella (14.0 %). In the unadjusted analysis, the catch-up vaccination rate was 70.6 % for tetanus, 50.9 % for measles, 47.7 % for rubella, 40.0 % for mumps, and 23.9 % for varicella. In the weighted analysis, the study-abroad group had significantly higher catch-up vaccination rates for measles (54.6 % vs. 29.8 %, P = 0.039), rubella (53.0 % vs. 22.1 %, P < 0.001), and varicella (26.8 % vs. 10.9 %, P = 0.002), whereas the non-study-abroad group had a higher catch-up vaccination rate for tetanus (62.4 % vs. 78.4 %, P = 0.024).

Conclusion: Compared with other travelers, the catch-up vaccination rate among travelers studying abroad was higher for measles, rubella, and varicella, but lower for tetanus. In clients planning to study abroad, vaccinations required for travel should be recommended in addition to those required by the host institution, and vaccination against highly infectious diseases with potential for complications, such as measles, rubella, mumps, and varicella, should be recommended to clients traveling for reasons other than studying abroad.

出国留学对年轻人补种疫苗的影响：利用日本旅行前咨询登记处进行的研究1。

目的：研究出国留学对年轻成人旅行者旅行前咨询期间麻疹、风疹、腮腺炎、水痘和破伤风疫苗补种覆盖率的影响：这项回顾性队列研究分析了日本旅行前咨询登记处（J-PRECOR）的数据，研究对象是有儿童疫苗接种记录的 18-21 岁的个人。研究采用倾向得分加权法估算了对接受补种的参与者比例的平均治疗效果：在 1091 名符合条件的参与者中，流行性腮腺炎（65.7%）和水痘（49.0%）的补种需求最高，麻疹（9.9%）和风疹（14.0%）的补种需求最低。在未调整分析中，破伤风的补种率为 70.6%，麻疹为 50.9%，风疹为 47.7%，流行性腮腺炎为 40.0%，水痘为 23.9%。在加权分析中，出国留学组的麻疹（54.6% 对 29.8%，P = 0.039）、风疹（53.0% 对 22.1%，P < 0.001）和水痘（26.8% 对 10.9%，P = 0.002）补种率明显较高，而非出国留学组的破伤风补种率较高（62.4% 对 78.4%，P = 0.024）：结论：与其他旅行者相比，出国留学人员的麻疹、风疹和水痘疫苗补种率较高，但破伤风疫苗补种率较低。对于计划出国留学的人，除了建议他们接种所在机构要求的疫苗外，还应建议他们接种旅行所需的疫苗，并建议因留学以外的原因出国的人接种麻疹、风疹、流行性腮腺炎和水痘等可能引起并发症的高传染性疾病的疫苗。

期刊介绍： The Journal of Infection and Chemotherapy (JIC) — official journal of the Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases — welcomes original papers, laboratory or clinical, as well as case reports, notes, committee reports, surveillance and guidelines from all parts of the world on all aspects of chemotherapy, covering the pathogenesis, diagnosis, treatment, and control of infection, including treatment with anticancer drugs. Experimental studies on animal models and pharmacokinetics, and reports on epidemiology and clinical trials are particularly welcome.
