Abstract:
OBJECTIVETo examine the influence of three-booster-doses hepatitis B vaccines on children with normal and high antibody response to primary vaccination.
METHODSAntibody against hepatitis B surface antigen (anti-HBs) were detected after primary vaccination and children with normal or high response to hepatitis B primary vaccination at infancy, were identified. Children who were given three booster doses were selected to form the booster group and who were given no booster dose were 1∶1 matched with the same gender and residence to form the control group. Blood samples were obtained from all the participants and tested for anti-HBs and anti-HBc, 5 years after the primary vaccination.
RESULTSThe positive rates of anti-HBs response to primary vaccination were 97.39% (224/230, 95% CI: 94.41%-99.04%) in the booster group and 53.91% (124/230, 95% CI: 47.24%-60.48%) in the control group (P<0.05), 5 years after the primary vaccination. Geometric mean concentration (GMC) of anti-HBs were 1 140.02 (887.46-1 464.46) mIU/ml in the booster group and 11.53 (8.73-15.23) mIU/ml in the control group (P<0.05). The prevalence rates of breakthrough HBV infection were 0.87% (2/230) in the booster group and 2.17%(5/230) in the control group (P>0.05). RESULTS from the multivariable analysis showed that the booster doses (OR=38.75, 95%CI: 16.23-92.54) and the level of anti-HBs after the primary vaccination (OR =3.06, 95%CI:1.51-6.17) were independently associated with the positive rates of anti-HBs, 5 years after the primary vaccination (P<0.05).
CONCLUSIONPrograms with three booster doses to children that showing normal and high antibody response to primary vaccination could improve the persistence of anti-HBs but possibly would not be able to prevent the HBV infection.
