Abstract |
To evaluate proportion and predictors of poor response in infants and appraise booster seroprotection, we surveyed 2047 infants in Shanghai and detected antibody to hepatitis B (HB) surface antigen (anti-HBs). Poor responders were randomized into 2 groups, given booster with 5 µg and 10 µg hepatitis B vaccine ( HepB), respectively. Proportion of infants with titer <10 mIU/mL and 10 to 99 mIU/mL was 1.86% and 15.14%, respectively. Multivariate logistic regression suggested infants of male, aged 13 to 18 months, premature, administered with 5 µg HepB or mother positive for HB surface antigen ( HBsAg) and HBe antigen ( HBeAg) would more likely develop worse response. Difference of geometric mean concentration between the first and full booster was not statistically significant both for 5 µg and for 10 µg HepB groups. The seroprotective rate were higher for infants with 10 µg HepB than those with 5 µg HepB (P > .05). Therefore, it is concluded that booster for poor vaccinees with 10 µg HepB could achieve satisfactory seroprotection.
