CONTEXT Hepatitis B Virus expanded program on immunization (EPI) started on 1993 in Iran. Most surveys have assessed the level of response to vaccine by measuring the titers of anti-HBs. This meta- analysis aimed to summarize the Iranian published data on the rate of vaccine-responders versus non-responders. Moreover, the impact of variables such as age, gender, type of vaccine, etc. on the lev...
BACKGROUND Injection drug users (IDUs) are at high-risk for hepatitis B virus (HBV) and HIV. Due to concerns about non-adherence to multi-dose vaccine regimens however, IDUs are severely under-immunized against HBV and have been excluded from phase III trials of multi-dose candidate HIV vaccines in the United States. METHODS Through a randomized controlled trial, we compared the effectiveness...
background hepatitis b virus (hbv) is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma (hcc). hb vaccination is an essential step in the prevention of the disease and its consequent complications. objectives immune status of medical personnel in teaching hospitals of khuzestan is not well known. since these personnel are usually at risk of needle stick and other...
INTRODUCTION Previous studies have indicated that the patients with psychiatric illness were at higher risk of hepatitis B virus (HBV) infection. However, the efficacy of hepatitis B vaccine in schizophrenia patients remains unclear. METHODOLOGY Between June 2014 and January 2015, 415 schizophrenia patients and 3,038 controls who had been routinely immunized as infants were recruited in the p...
OBJECTIVES The knowledge about outcomes of infant vaccination against HBV infections using the DPT-HepB-Hib vaccine in Ghana is limited. This study therefore investigated the levels of immunity to HBV among children who received the DPT-HepB-Hib vaccine and HBsAg carriage in non-responders. Correlates for non-response or poor response were also investigated. METHODS Cross-sectional study. A m...
BACKGROUND Hepatitis B (HBV) vaccination is an important preventive intervention for HIV-infected population. Data regarding booster HBV vaccine for persons with low HBV surface antibody (sAb) titers after vaccination in this immunocompromised population is lacking. METHODS We randomized 60 HIV-infected subjects lacking HBV protection after completion of 3 doses of HBV vaccine to receive a bo...
BACKGROUND A therapeutic vaccine for chronic hepatitis B virus (HBV) infection that enhances virus-specific cellular immune responses is urgently needed. The "prime-boost" regimen is a widely used vaccine strategy against many persistence infections. However, few reports have addressed this strategy applying for HBV therapeutic vaccine development. METHODOLOGY/PRINCIPAL FINDINGS To develop an...
AIM To assess the efficacy and safety of in vivo electroporation (EP)-mediated dual-plasmid hepatitis B virus (HBV) DNA vaccine vs placebo for sequential combination therapy with lamivudine (LAM) in patients with chronic hepatitis B. METHODS Two hundred and twenty-five patients were randomized to receive either LAM + vaccine (vaccine group, n = 109) or LAM + placebo (control group, n = 116). ...
background: hepatitis b virus (hbv) vaccination is a well-known, safe and effective way for protection against hbv infection; however, non-responders remain susceptible to infection with hbv. this is so important in patients with any kind of chronic liver disease, especially chronic hepatitis c virus (hcv) patients in whom acute hbv infection may lead to decompensation of liver disease. some of...
BACKGROUND Combination vaccines improve coverage, compliance and effectively introduce new antigens to mass vaccination programmes. This was a phase III, observer-blind, randomized study of GSK Biologicals diphtheria-tetanus-whole cell pertussis vaccine combined with hepatitis B and Haemophilus influenzae type b vaccines, containing a reduced amount of polyribosyl-ribitol-phosphate (PRP) and a ...
