Epidemiological Survey on Vaccination Rate of Neonatal Hepatitis B Vaccine and Carrier Rate of Maternal Hepatitis B Virus in 2003 in Wuhan City

Objective The present study was designed to understand the initial vaccination rate of the neonatal anti—hepatitis B vaccine，the whole range vaccination rate and the infection rate of maternal hepatitis B virus in Wuhan city．Methods Delivery rooms of all hospitals and planned immunization sites in the city were investigated and statistically analyzed using Microsoft Excel 2000．Resuits The initial immunization rate of the neonatal hepatitis B vaccine was 98.51％，with a timely rate of 95.32％．The urban areas were better than the suburbs in the aspects．The rate of full-course immunization was 86.87％，the suburbs better than the urban areas，and per-manent population better than floating population．The screening rate of hepatitis B of postnatal women in the whole city was 66.29 and the carrier rate 6.04％．The anti-hepatitis B immunoglob—ulin rate of the neonatals whose mothers carried HBV was 84.24％．And the urban areas was bet-ter than the suburbs in hepatitis B screening and the neonatal anti—hepatitis B immunoglobulin im-munization．Conclusion The initial immunization rate and the timely rate have been encouraging since the implementation of free immunization of neonatal hepatitis B vaccine in the whole city，but the full-course rate is less satisfying．There exists a weakness in the planned immunization， and particularly the difficulty in the management of floating population in the urban areas inter-feres with planned immunization substantially．The immunization of hepatitis B vaccine in adoles— cent should be covered in the immunization programme．
