关于麻疹血清阳性率的数据有限,腮腺炎,风疹,以及日本紧急医疗技术人员(EMT)中的水痘(MMRV)。本研究旨在根据日本感染预防和控制协会指南,评估针对EMT中额外疫苗接种的MMRV的足够免疫力。作为EMT疫苗接种计划的一部分,进行了一项回顾性观察研究。每位参与者都接受了病史评估,疫苗接种史,和血清学使用日本感染预防和控制学会建立的标准。总的来说,85名急救人员(平均年龄,31岁;男性,92.9%)包括在内。在包括的急救人员中,32(37.6%),54(63.5%),46(54.1%),84例(98.9%)麻疹血清呈阳性,风疹,腮腺炎,和水痘,分别,而1(1.2%),6(7.1%),5(5.9%),0(0%)为血清阴性。此外,48(56.5%),27(31.8%),45(52.9%),8名(9.4%)EMT额外接种了麻疹疫苗,风疹,腮腺炎,和水痘,分别。本研究表明,EMT对MMRV并不完全免疫,这强调了确认免疫状态和额外疫苗接种要求以预防职业感染的必要性。
Limited data are available regarding the seroprevalence of measles, mumps, rubella, and varicella (MMRV) among emergency medical technicians (EMTs) in Japan. The present study aimed to review a project to evaluate adequate immunity against MMRV for the requirement of additional vaccination among EMTs in accordance with the Japanese Society for Infection Prevention and Control
guidelines. A retrospective observational study was conducted as part of a vaccination program for EMTs. Each participant was evaluated for medical history, vaccination history, and serology using the criteria established by the Japanese Society of Infection Prevention and Control. In total, 85 EMTs (median age, 31 years; male, 92.9%) were included. Among the included EMTs, 32 (37.6%), 54 (63.5%), 46 (54.1%), and 84 (98.9%) were seropositive for measles, rubella, mumps, and varicella, respectively, whereas 1 (1.2%), 6 (7.1%), 5 (5.9%), and 0 (0%) were seronegative. Furthermore, 48 (56.5%), 27 (31.8%), 45 (52.9%), and 8 (9.4%) EMTs received an additional dose of vaccines for measles, rubella, mumps, and varicella, respectively. The present study suggests that EMTs are not fully immune to MMRV, which highlights the need for confirming the immune status and additional vaccination requirement to prevent occupational infections.
