摘 要：Objective:To assess levels of HBs Ab amongst infants who received hepatitis B vaccine in the Expanded Program on Immunization in ***:A cross-sectional study was carried out at 16 community health centers from February 2016 to July *** infants were tested for HBs Ab and HBs *** questionnaires were used to collect relevant information about the demographics of the parents/caregivers and their infants after physical ***:A total of 199 eligible infants were selected with a mean age of(17.3±4.5)*** antibody levels with HBs Ab≥10 m IU/m L were detected in 68.3%of *** these,antibody levels from 10 to 99 m IU/m L were 48.5%of those tested and antibody levels≥100 ml U/m L were recorded as 51.5%.No cases were recorded of being infected with hepatitis B *** rate of positive HBs Ab level in those who were not wasting and≥18 months old was less than that among those who were18 months old(OR 0.49,95%CI:0.26-0.92,P0.05)while the infants with wasting and18 months were less likely to be positive HBs Ab than those who were not wasting and of the same age group(OR 0.15,95%CI:0.04-0.55,P0.05).Conclusions:Seroprotection against hepatitis B virus was low in the infants tested(at 68.3%),which suggests that the hepatitis B vaccine should be administered with one additional dose for infants between 12 and 24 months of age,particularly those with wasting.
