ABSTRACT

Our study states that the routine hepatitis B vaccination program has led to a significant decrease in the incidance of HBV infection and it is therefore necessary to continue the programme in order to achieve public awareness

HBsAg seropositivity was determined as 1.5% in children who were born after routine vaccination program and as 19.2% in children who were born before the vaccination program

Data of 200 children born after the initiation of routine hepatitis B vaccination and 104 children born before routine hepatitis B vaccination were evaluated. Presence of HBsAg, AntiHBs, AntiHBcTotal, HBeAg and antiHBe markers were determined with ELISA

Hepatitis B Virus (HBV) chronic infection is related to the age of the infected person. Chronic carriage most likely occurs due to HBV infection in infancy. Therefore, it is important to prevent infection in infancy. The efficacy of hepatitis B vaccine in preventing HBV infection in children has been proven. This study aimed to determine the incidence of HBV infection after routine Hepatitis B vaccination program in our country
