Objective: To evaluate the safety and antibody responses to aerosolized Attenuvax measles strain, Jeryl Lynn mumps strain and RA 27/3 rubella component of an MMR vaccine in adults, before assessing the booster administration of this vaccine in children. Methods: A pilot study to evaluate safety and antibody responses of MMR II (Merch Sharp & Dhome Corp., Whitehouse Station, NJ 08889, USA) components administered by aerosol was carried out in 27 healthy adults of 21 to 38 years of age. All participants were followed-up during 28 days following immunization for detection of clinical adverse events. Immune response was evaluated by plaque reduction neutralization test for measles, and commercial ELISA kits for rubella and mumps. Results: Only mild clinical adverse events were noted. Despite high levels of baseline seropositivity to all vaccine components, seroresponses to measles, rubella and mumps occurred in 44%, 15% and 41%, respectively. Conclusions: These outcomes compare favorably with earlier studies of other MMR vaccines given by aerosol. Further evaluations on safety and booster immune response should be performed in children.展开更多

Specific rubella IgM antibody test was carried out on all samples that were negative for measles IgM antibody and for sero-diagnosis of CRS.Results:Through the surveillance program for measles,the samples received for rubella had increased five fold from 365 in 2004 to 1 522 in 2007.Positive rubella cases detected had also increased from 4.1%in 2004 to 33.2%in 2007.The age group 11 to 20 years accounted for 73.6%of rubella cases confirmed in 2008,with a higher incidence among males than females.Positive rubella IgM was detected in 25 CRS cases during the 6 year period between January 2003 and December 2008.Conclusion:The measles elimination program had contributed to significant progress in the control of rubella,with the majority of rubella cases detected through this strategy.Since rubella is not notifiable in Malaysia,this integrated measles and rubella surveillance should be continued.However,to enhance the progress,specific targets should also be established in the national program to eliminate rubella and CRS.展开更多

文摘目的分析甘肃省12岁以下儿童接种麻腮风联合减毒活疫苗(MMR)后30 d内发生单纯性热性惊厥(SFS)特征。方法筛选甘肃省2021年1月1日至2023年12月31日电子病历库中诊断为“热性惊厥”个案,利用病例身份信息匹配甘肃省免疫规划信息系统中该病例的接种信息,采用观察性流行病学方法分析12岁以下儿童出现SFS的流行特征及接种MMR 30 d内SFS发生风险。结果共纳入10614例SFS儿童患者,12岁以下儿童SFS总体发生率为92.42/10万,其中12~24月龄儿童发生率最高,为297.67/10万,男性儿童发生SFS风险高于女性儿童(RR值为1.61,P<0.001)。接种MMR后30 d内发生SFS风险较未接种该疫苗的高(RR值为2.66,P<0.001)。接种第1剂次的发生率(27.98/10万)较第2剂次(18.48/10万)高,12~24月龄儿童在接种第1剂次MMR 6~14 d SFS发生风险较<12月、25月~6岁组高(RR值分别为4.06和2.64,P<0.001)。结论12~24月龄儿童在接种MMR后6~14 d SFS发生风险增加,以12~24月龄儿童最为常见,应高度关注高风险人群并加强对SFS监测。
