2023年2月第30卷第2期不同年龄儿童接种乙肝疫苗后的免疫应答效果观察梁振昌1,郭浩彬1,黄淑婷2(1中山市石岐苏华赞医院检验科,广东中山528400;2中山市石岐街道社区卫生服务中心公共卫生科,广东中山528400)【摘要】目的探讨不同年龄儿童接种乙肝疫苗后的免疫应答效果。方法选取2014年1月至2019年12月于石岐街道社区卫生服务中心行乙肝疫苗接种的1976例儿童为研究对象,采用化学发光法检测全部儿童的5项乙肝标志物,分析乙肝疫苗接种后的免疫应答效果。结果1976例儿童中,有免疫应答1845例,占比93.37%,其中高免疫应答1248例,占比63.16%,低免疫应答597例,占比30.21%;无免疫应答131例,占比6.63%。<2岁儿童的免疫应答率为98.26%,高于2~5岁儿童的92.98%以及>5岁儿童的85.80%,差异有统计学意义(P<0.05)。结论接种乙肝疫苗能够有效预防乙肝感染,且免疫应答率伴随着年龄的增长而呈下降趋势,临床需尽早接种,以提高免疫应答率。【关键词】儿童;乙肝疫苗;免疫应答;乙肝标志物中图分类号:R512.6+2文献标识码:Adoi:10.3969/j.issn.1674-4659.2023.02.0285ObservationontheImmuneResponseEffectsofChildrenofDifferentAgesAfterHepatitisBVaccinationLIANGZhenchang1,GUOHaobin1,HUANGShuting2(1ClinicalLaboratory,ShiqiSuHuazanHospital,Zhongshan528400,China;2DepartmentofPublicHealth,ShiqiStreetCommunityHealthServiceCenter,Zhongshan528400,China)[Abstract]ObjectiveToexploretheimmuneresponseeffectsofchildrenofdifferentagesafterhepatitisBvaccination.MethodsAtotalof1976childrenwhoreceivedhepatitisBvaccinationinShiqiCommunityHealthServiceCenterfromJanuary2014toDecember2019wereselectedastheresearchobjects.FivehepatitisBmarkersofallchildrenweredetectedbychemiluminescencemethod,andtheimmuneresponseeffectafterhepatitisBvaccinationwasanalyzed.ResultsAmongthe1976children,1845caseshadimmuneresponse,accountingfor93.37%,ofwhich1248caseshadhighimmuneresponse,accountingfor63.16%,and597caseshadlowimmuneresponse,accountingfor30.21%;131caseshadnoimmuneresponse,accountingfor6.63%.Theimmuneresponserateofchildren<2yearsoldwas98.26%,higherthan92.98%ofchildrenaged2~5yearsoldand85.80%ofchildren>5yearsold,withstatisticallysignificantdifferences(P<0.05).ConclusionsHepatit...
