BACKGROUND Hepatitis B vaccine and hepatitis B immunoglobulin are considered for newborn infants of HBsAg-positive mothers to prevent hepatitis B infection. OBJECTIVES To assess the beneficial and harmful effects of hepatitis B vaccines and hepatitis B immunoglobulin in newborn infants of HBsAg-positive mothers. SEARCH STRATEGY Trials were identified through The Cochrane Neonatal Group Cont...

Hepatitis B: Hepatitis B infection can be prevented. If your work or lifestyle exposes you to the virus, we encourage you to get a Hepatitis B vaccine. If you have not had Hepatitis B vaccine, you can begin your Hepatitis B vaccine series immediately after being exposed. Hepatitis C: There is no vaccine to prevent Hepatitis C. If exposed, you must be tested regularly to make sure you have not b...

Background & Aims: Hepatitis B virus is one of the causes of acute and chronic hepatitis. Due to multiple hospitalization and blood transfusion, thalassaemic patients are at higher risk of this infection. Duration of the immunity after vaccination in this high-risk group and the need for booster vaccination is uncertain. The aim of this study was to find antibody titration and immunity to Hepat...

background: hepatitis b infection is a major public health problem worldwide. dental students who are frequently in contact with body fluids like blood and saliva are still at high risk for hbv exposure. the aim of this study was to evaluate the effectiveness of hbv vaccine and personal factors associated with serologic evidence of the immune response. methods: a descriptive-cross sectional stu...

introduction: vaccination with the major surface antigen of hepatitis b virus (hbsag) induces anti-hbs antibody production and level of 10 iu/l is considered protective. it has been shown that the level of anti-hbs antibody does wane after vaccination. the aim of this study was to evaluate the persistence of anti-hbs antibodies in healthy iranian children 10 years after primary vaccination. met...

conclusions dental academics were unsure about the means of infection and prevention against hbv. many of them had not completed the immunization scheme and did not have the test of seroconversion. the serological analysis revealed unprotection, even after students completed the vaccination schedule. results of the 179 students surveyed, 58.1% knew about the degree of virulence of the hepatitis...

Background & Objectives: Hepatitis B is one of the major health problems in the world. Health care workers (HCWs) are at high risk of acquiring hepatitis B virus. The aim of this study was to evaluate the prevalence of HBV infection and the immune response to HBV vaccine among the HCWs in Babol, northern...

hepatitis c virus (hcv) infection is highly prevalent in thalassemic patients, and this may decrease the serum antibody response to hepatitis b virus (hbv) vaccine. there is also some alteration of the immune system in multi-transfused thalassemic patients, as a consequence of iron overload. we investigated whether hcy infection may reduce the effectiveness of hby vaccine in multi - transfused ...
