An antibody population which reacts only with human sickle cell hemoglobin (HbS) and not with normal human hemoglobin, has been isolated from goat, sheep, and guinea pig antisera. These antibody populations termed anti-Val (Val), isolated from an individual goat (no. 6) and sheep (no. 26) have been used to elicit anti-idiotypic responses in rabbits. These anti-idiotypic sera were used to study ...
INTRODUCTION There are controversies over the long-term persistence of post vaccination immunity to hepatitis B and the need for booster doses of the vaccine. The aim of this study was to verify antibody levels of antibody against hepatitis B virus surface antigen (anti-HBs) in children aged 1 to 15 years who received vaccination against hepatitis B in the central province of Iran, Semnan. MA...
Immunogenicity of recombinant hepatitis B vaccine: comparison of two different vaccination schedules
BACKGROUND Neonatal immunization with hepatitis B (HB) vaccine induces protective levels of antibody (anti-HBs > or =10 IU/L) in a majority of vaccines. However, the duration of protection after HB vaccination in infants is unknown. A smaller proportion of children vaccinated beginning at birth with three doses of HB vaccine were found to have protective titers 5-10 years after initial vaccinat...
Background and Purpose : The prevalence of Hepatitis B in ÜSÂ was reported 0.5- 0.1 % while in Ïran is 1.6- 6.5 %. Ït was reported that the titer of antibody three days after vaccination was 79-90 %. The titer of antibody decreases with the pass of time, and age has a significant role in the respones to vaccination. This study was performed in order to evaluate the HBS titer after vaccination...
To evaluate the relationships between human T lymphotropic virus type I (HTLV-I) and hepatitis virus type B (HBV) infections, we compared both individual and geographical distributions of carriers of HTLV-I and HBV, and antibody positives to HBV in two ATL-endemic islands in Kyushu, Japan. The positive rates of antibodies to HTLV-I (anti-HTLV-I-Ab) in sera among healthy inhabitants older than 3...
Background and purpose: The aim of the present study was to identify the true extent of non-responsiveness in children vaccinated against Hepatitis B virus (HBV) ten years ago at birth whom were serologically susceptible to HBV,and had poor antibody response to booster HBV vaccine. Materials and Methods: Twenty low-and non-responding 11.5 years old children recuited in by another study rec...
background: for healthcare workers, sometimes the conventional hepatitis-b virus (hbv) vaccination schedule might not provide seroconversion rapidly enough. the aim of this study was to compare the efficacy of conventional hbv vaccination with an accelerated schedule (days 0-1-21). normal 0 false false false en-us x-none ar-sa materials and methods: in this randomized clinical trial, 161 health...
BACKGROUND Dental health care providers are at risk of infection with hepatitis B virus (HBV). Dentists can occupationally become infected with HBV through needle sticks or exposure to blood and other body fluids. OBJECTIVES To evaluate anti-HBs antibody titer in students, professors, clinical assistants and non-clinical staff of Faculty of Dentistry, Tehran University of Medical Sciences (TU...
BACKGROUND With a technical improvement of the assay system, automated immunoassay analyzers for hepatitis B surface antibody (anti-HBs) are widely used. However, some discrepancies between assays are still being reported. We compared the qualitative and quantitative results of three kinds of anti-HBs assays. METHODS Serum samples were collected from 517 patients and anti-HBs were determined ...
