Abstract:
The aim of this study was to determine the hepatitis B virus infection among
vaccinated children of age 1-4 years in Al Hasseissa Pediatric hospital.
A total of 90 blood specimens were collected from children suspected
having hepatitis B virus infection during the period from April to June 2012.
Serological analyses of blood were performed to detect hepatitis B surface
antigen using ICT and ELISA. The specimens were firstly checked by
screening (ICT) and then by ELISA. The result showed that 87 (97%) of
vaccinated children were seronegative by ELISA for HBV infection and
3(3.3%) were seropositive for HBV where as the screening test using ICT
did not show reaction .
