BACKGROUND In 1999, the American Academy of Pediatrics and U.S. Public Health Service recommended suspending the birth dose of hepatitis B vaccine due to concerns about potential mercury exposure. A previous report found that overall national hepatitis B vaccination coverage rates decreased in association with the suspension. It is unknown whether this underimmunization occurred uniformly or wa...

Background: Hepatitis B virus (HBV) infection causes significant morbidity and mortality worldwide. Occupational exposure of health care workers and medical students increases their risk of acquiring HBV infection, and many authorities recommend vaccination. However, significant proportions of health care workers do not receive HBV immunization, and remain at increased risk to HBV infection. Ob...

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: There is a controversy about the relation between anti-hepatitis B (anti-HBs) antibody level and obesity. We designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. Methods: In this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. Cases were selected from a referral clinic for obesity and a referral hepa...

BACKGROUND Homosexual contact is a major risk factor for acute hepatitis B infection. This study explores how many and which men who have sex with men (MSM) are reached by the ongoing hepatitis B vaccination programme in The Netherlands (started in 2002), and investigate reasons for non-participation and non-compliance. METHODS In this cross-sectional study, on the basis of ethnographic mappi...

The four main approaches to immunisation against hepatitis B are: vaccination of high risk babies; universal adolescent immunisation; universal infant immunisation; and vaccination of everybody. Universal antenatal screening would permit identification of carrier mothers and immunisation oftheir babies. Vaccination of adolescents would provide protection close to the time when risk of exposure ...

Background and aims: Hepatitis B vaccination is the most successful way to prevent the virus infection. Serum concentration of vitamin D has recently been proposed as a novel predictor of response to antiviral treatment in chronic hepatitis infection. The main target of this paper was to review the recent knowledge regarding the association between obesity and vitamin D level and immune respons...

Hepatitis A, B, and C are important viral hepatitis infections in the Thai population. Hepatitis B vaccination was included in the Thai Expanded Program on Immunization (EPI) 10 years ago. In addition, the seroprevalence of hepatitis A has significantly changed in the last two decades. This study was done to evaluate current risk groups for hepatitis A and B infections and identify the magnitud...
