Abstract:

Objective To evacuate the immunogenicity of measles-mumps-rubella combined vaccine (MMR), explore its influencing factors, and survey the attitude to vaccination in recruits. Methods The cluster sampling method was used to select recruits from two boot camps stationed in Guangdong in September 2017 as the research objects. A total of 396 people from the boot camp 1 were selected to study the immunogenicity and influencing factors of MMR, and a cognitive survey of vaccine was conducted in 473 people from the boot camp 2. The recruits' antibody titers before and after MMR vaccination were tested, and a questionnaire survey was conducted. χ2 test was used to analyze the difference of antibody positive rate before and after vaccination. After data transformation, normality test, and homogeneity test of variance, the antibody geometric mean concentration (GMC) was statistically analyzed by independent sample t test or F test. Results After MMR vaccination, the antibody positive conversion rates of measles, mumps, and rubella in the 396 people from the boot camp 1 were 100.00%, and the antibody GMC of measles, mumps, and rubella were 1 191.67 mIU/ml, 1 663.62 U/ml, and 144.59 IU/ml respectively, which were 1.73 times, 4.79 times, and 4.09 times of those before vaccination. The antibody levels after vaccination were significantly higher than those before vaccination (all P<0.05). After vaccination, the antibody GMC of the soldiers with negative antibody before vaccination was lower than those with positive antibody before vaccination, and the difference was statistically significant in the mumps and rubella (both P<0.05). The study found that age, nationality, education background, place of enlistment, family economic status, smoking, drinking, work before enlistment, intimate contact with the opposite sex, and chronic gastroenteritis had no significant effects on the antibody concentration after MMR vaccination. According to the survey, the vast majority of people in the boot camp 2 wanted to know the knowledge related to the vaccine [97.25% (460/473)] and believed that vaccination could effectively prevent the corresponding diseases [90.49% (428/473)], but only 72.52% (343/473) were willing to inoculate vaccine. The main reason for their reluctance was vaccine safety (53.85%). Conclusions Domestic MMR can produce good immunogenicity in recruits. Vaccine security events make a negative influence on vaccination willingness, and the publicity and education of vaccination in troops should be strengthened.

摘要: 目的 了解部队新兵接种麻腮风疫苗(MMR)的免疫效果、影响因素及对预防接种的态度。方法 采用整群抽样的方法选择驻广东某部2017年9月入伍的2个新兵营作为研究对象。选择新兵营一396人开展麻腮风联合减毒活疫苗免疫效果及影响因素研究,选择新兵营二473人开展疫苗的认知调查。对新兵接种MMR前后的抗体滴度进行检测,并开展问卷调查。用χ2检验分析疫苗接种前后抗体阳性率之间差异,抗体几何平均浓度(GMC)进行数据变换、正态性检验和方差齐性检验后用独立样本t检验或F检验进行统计分析。结果 MMR接种后,新兵营一396人麻疹、腮腺炎和风疹抗体阳转率均为100.00%;MMR接种后麻疹、腮腺炎和风疹GMC分别为1 191.67 mIU/ml、1 663.62 U/ml和144.59 IU/ml,是接种前的1.73倍、4.79倍和4.09倍,接种后抗体水平显著高于接种前(均P<0.05);接种前抗体阴性的新兵接种后抗体GMC低于接种前抗体阳性的新兵,其中腮腺炎和风疹差异均有统计学意义(均P<0.05)。研究中没有发现年龄、民族、学历、入伍地、家庭经济状况、吸烟、喝酒、入伍前工作、与异性有过亲密接触、有慢性胃肠炎对MMR接种后的抗体浓度产生影响。调查显示,新兵营二绝大多数官兵希望了解与疫苗有关的知识97.25%(460/473),认为接种疫苗能有效预防相应疾病90.49%(428/473),但愿意接种疫苗的仅72.52%(343/473),不愿意接种的主要原因为疫苗安全问题(53.85%)。结论 国产MMR在新兵中接种能产生良好的免疫效果;疫苗安全事件影响官兵的接种意愿,应加强宣教。
