Background:Hepatitis B virus (HBV) is the leading cause of viral hepatitis and about 240 million people worldwide are chronic carriers. The virus isreported to be widely prevalent in Ethiopia and routine vaccination of children has been initiated in the country recently. We assessed the sero-prevalence of HBVinfection and sero-protection of HBVvaccine among children in Jimma town

Methods:A community based cross-sectional study was conducted among 900 children with 5-9 years-old betweenJune and December 2016. A simple random sampling technique was employed to recruit study participants by proportional allocation into different Kebeles of Jimma town. Data were collected using pretested questionnaire and about 3-5ml of blood sample was collected and tested for HBsAg, anti-HBc and anti-HBs using ELISA (Bio-rad, Monolisa, Lacquote, France).Data were analyzed using chi-square and logistic regression test.

Result:HBsAg and anti-HBc prevalence among all participants was3.5% and 3.8%, respectively. The prevalence of HBsAg among vaccinated and non-vaccinated was 2.1% and 7.0% whereas anti-HBc positivity was 1.1% and 6.2%, respectively. It was also found that 58.4% of vaccinated children retained a protective level of HB surface antibodies, ≥ 10 mIU/ml with the overall mean of 50 mIU/ml.
