An evaluation on immunization effect and the influencing factors after revaccination with 60 μg hepatitis B vaccine among non-response adults / 预防医学

ABSTRACT

Objective To explore vaccine immune effects of 60μg hepatitis B on adults who have no response to hepatitis B vaccination.Methods A Total of 689 healthy adults who were HBsAg and anti -HBs negative were selected,and they were received 3 doses of hepatitis B vaccine at dosage 10 μg.Those with anti-HBs<10 IU/L detected after full series vaccination were given 1 dose of hepatitis B vaccine at dosage 60 μg.One month later,anti-HBs detection was conducted for them.Results The non -responsiveness rate was 17.71% after primary hepatitis B vaccination.The multivariate logistic regression analysis showed that risk factors for primary non-responsiveness were the history of surgical operation, immunization schedule and "anti-HBc alone".The anti-HBs positive rate was 95.5 1% in 89 re-vaccinated people, and the geometric mean titers of anti -HBs(GMT)was 585.39 IU/L.Conclusion Re -immunization of hepatitis B vaccine at dosage 60 μg has good immunogenicity in people who have no response to primary vaccination,and weight control may improve the effect of hepatitis B re-immunization.
