Liver disease, particularly viral hepatitis, is increasingly common. The most frequent causes of long-term, or chronic, viral hepatitis are persistent infections with the hepatitis B or hepatitis C virus. Worldwide, 400 million people are chronic carriers of the hepatitis B virus [1]. Each year, between 500,000 to 1.2 million people die from progression of this viral infection, making it the 10...

BACKGROUND Hepatitis B vaccination for healthcare workers (HCWs) is a key component of the WHO Hepatitis B Elimination Strategy 2016-2021. Data on current hepatitis B vaccine coverage among health care workers in Sub-Saharan Africa are scarce, but these data are vital for effective programming. We assessed the proportion of HCWs vaccinated for hepatitis B and the factors associated with adequat...

The plasma derived vaccine for hepatitis B became commercially available in 1982 but its availability was limited. The new generation of hepatitis B vaccine (recombinant rDNA yeast derived) can be produced in greater quantities at a comparable cost. Recombinant HBV vaccine given in infancy is highly immunogenic. Most infants develop antibody titre well above 10 m1U/ml, the level associated with...

The National Center for Education Statistics reported that between 1990-2005 the number of children receiving special education services (SES) rose significantly, and then, from 2004-2012, the number declined significantly. This coincided with the introduction of Thimerosal-containing hepatitis B vaccine in 1991, and the subsequent introduction of Thimerosal-reduced hepatitis B vaccine in the e...

This study identified the impact of hepatitis B vaccine over reducing incidence of this disease in Paraná State, between 2001 and 2011, and discussed the role of nursing in immunization. Descriptive documental and quantitative research. Utilized secondary data of hepatitis B, between 2001 and 2011 and vaccination coverage of hepatitis B vaccine between 1995 and 2011 in Paraná State, available i...

background recommendations to immunize healthcare workers (hcws) against hepatitis b are well known. however, a proportion of individuals do not respond to the primary standard three-dose hb vaccination schedule. conclusions both the single- and double-dose hb vaccines were adequately immunogenic, and the double-dose hb vaccine was not significantly more immunogenic than the single-dose vaccine...

results before boosting, among 176 boosted individuals, 75 (42.6%) had hbsab 10 iu/l and were considered seroprotected. among 101 serosusceptible persons, more than 80% of boosted individuals showed more than twofold increase in cytokines concentration, which meant positive hbsag-specific cell-mediated immunity. mcl of both cytokines after boosting in giv were decreased more than twofold, possi...

chronic hepatitis b is still a major public health issue despite the successful prophylactic vaccination attempts. chronicity of hepatitis b virus(hbv) is mainly due to its ability to debilitate host's immune system. therefore, major measures have been taken to stop this process and help patients with chronic hepatitis b infection recover from their illness. while satisfactory results have...

objective: preventing communicable diseases in the armed forces (af) of a country is considered as a national interest and has a great importance. there are limited data on the efficacy of vaccination of the navy personnel. this study was designed to evaluate both the safety and the immunogenicity of a recombinant hepatitis b (hb) vaccine made by pasteur institute of iran (ipi-rhb), in this tar...

BACKGROUND Tajikistan, considered highly endemic area for hepatitis B virus (HBV) in a pre-vaccine era, introduced hepatitis B vaccine in 2002 and reported ≥80% coverage with three doses of hepatitis B vaccine (HepB3) since 2004. However, the impact of vaccine introduction has not been assessed. METHODS We tested residual serum specimens from a 2010 national serosurvey for vaccine-preventable...
