We examined long-term anti-hepatitis A virus antibody persistence in Argentinean children 10 years after the initial study in which they received 2 doses of inactivated hepatitis A vaccine (Avaxim 80U). Of the 111 children, 48 from the initial trial were enrolled. Of 48, 47 (97.9%) participants had serum anti-hepatitis A virus antibody titers > or =20 mIU/mL, with the geometric mean concentration of 390.91 (+/-370.14) mIU/mL; (95% confidence interval, 282.2-499.5 mIU/mL), range, 36 to 1860.
我们在阿根廷儿童接种两剂甲型肝炎灭活疫苗（Avaxim 80U）10 年后，对他们的长期抗甲型肝炎病毒抗体持久性进行了研究。在最初的研究中，有 111 名儿童，其中 48 名参加了本次研究。在这 48 名儿童中，47 名（97.9%）参与者的血清抗甲型肝炎病毒抗体滴度>或=20 mIU/mL，几何平均浓度为 390.91（+/-370.14）mIU/mL；（95%置信区间，282.2-499.5 mIU/mL），范围为 36 至 1860。
