In addition, we wanted to show if there is any difference in children who were born after implementation of hepatitis B vaccine into national immunization programme. Material and Method: We studied 989 subjects, aged 2 months-16 years, who were admitted to our Department between 2004 January and 2005 July. We used x2 test to evaluate the serological results. Results: There is statistically significant decrease of antiHBs seropositivity with increasing age (x2: 72.8, p<0.00001). On the contrary, there is significant increase in ratio of antiHBc-IgG seropositivity with increasing age (x2: 27.2, p<0.0001). Conclusions: The ratio of antiHBs seropositivity is increasing in subjects born after implementation of hepatitis B vaccine into national immunization scheme, though not reached to targeted level yet.trinfo:eu-repo/semantics/closedAccessHepatitis B infectionMalatyaNational immunization schemeArticle41131352-s2.0-47249090383N/A
