摘要: We examined long-term anti-hepatitis A virus antibody persistence in Argentinean children 10 years after the initial study which they received 2 doses of inactivated hepatitis vaccine (Avaxim 80U). Of 111 children, 48 from trial were enrolled. 48, 47 (97.9%) participants had serum titers > or =20 mIU/mL, with geometric mean concentration 390.91 (+/-370.14) mIU/mL; (95% confidence interval, 282.2-499.5 mIU/mL), range, 36 to 1860.
