Seropositivity of antibody to hepatitis B core antigen among hepatitis B surface antigen-negative vaccinated individuals aged 5-12 years in North West Ethiopia.

Background: Infection with the hepatitis B virus (HBV) is still a major global public health concern, especially in Ethiopia. Evidence suggests that some children in Ethiopia who have received hepatitis B vaccinations are still contracting HBV.

Objective: The main aim of this study was to detect antibodies to hepatitis B core antigen (anti-HBc) among vaccinated hepatitis B surface antigen (HBsAg)-negative individuals in North-West Ethiopia.
