Hepatite B is one of the most important infection in the world. The best way to prevent hepatitis B infection is by getting the hepatitis B vaccine. The aim of this study was to evaluate level of HBs antibody titer of 10-18 years healthy students in Razavi Khorasan, North Khorasan and South Khorasan.
This study was a descriptive analytic research that was performed on 565 serum samples that were collected from 10-18 years healthy students with demographic information in Razavi Khorasan, North Khorasan and South Khorasan. HBs Ab titers were measured with immunochemiluminescence assay. Data were analyzed using Chi-Square and t test.
Out of 565 students, 20.6% in Razavi Khorasan , 20.1% in North Khorasan and 22.4% in South Khorasan had antibody in protective range (>10 IU/L). In addition, 79.85% of students were non-immune. There was no significant difference in antibody among level of education, and urban and rural location. The relationship between sex and titer of anti HBs was not statistically significant. The highest percentage of students with protective antibody was observed in 10 years old students (33.3%) and there was the lowest level of protective antibody in 18 years old (15.4%).
HBs Ab titer of students should be regularly evaluated because HBsAb level decreases after certain periods as age advances. Awareness of students about injection of booster dose of hepatitis-B vaccine is required.

Hepatitis B virus is the cause of acute and chronic hepatitis، cirrhosis and hepatocellular carcinoma. In the present، the only secure way to prevent hepatitis B is vaccination، but the vaccination is not 100% affective. Considering the importance of this، the efficacy of vaccination in high risk groups and health-care workers are at risk being involved with all types of hepatitis viruses. For reduction of hepatitis B infection among hospital staff these groups should be vaccinated against HBV besides using other standards for HBV prevention. The purpose of this study is to evaluate the anti-hepatitis B antibody among students of nurse’s aid school in Be''sat Hospital. Anti-hepatitis B antibody levels were measured using ELISA in 64 nurse’s aid students. the vaccination history of study population was unclear. 37 (57. 8%) cases were non-immune and 27 (42. 2%) cases were immune against HBV. Our results showed similarity with other studies. Several factors affected HBV immunization such as age، genetics، obesity، and smoking. This study showed that more than half of the people are non-immune. It should be noted that these people are in continuous contact with their classmates and patients so they should be evaluated for HBs antibody titer in different intervals.
