conclusions the palestinian and israeli official policies to give a booster dose for risk groups like medical students at anti-hbs level below 10 miu/ml should continue to ensure absolute protection. the currently-used vaccine and its time program cleared virus from students believed to have been exposed to the virus during their lifetime. background hepatitis b infection is a global public hea...

HBs vaccines were prepared by three different methods: 1) Heat inactivation (Krugman, et.al 1971)2) Ammonium sulphate precipitation followed by column chromatography (Sephadex G-200) 3) PEG-6000 (polyethylene glycol) precipitation followed by column chromatography using Sephadex G-200. Their efficacy was studied in guinea pigs, and the results compared with commercial Japanese vaccine (Gr...

background the impact of hepatitis b virus (hbv) vaccination campaigns on hbv epidemiology needs to be evaluated, in order to assess the long-term immunity offered by vaccines against hbv. objectives to evaluate the current status of anti-hbv vaccine coverage among healthcare workers (hcws) in southern italy, and to determine the long-term persistence of antibodies to hepatitis b surface antige...

conclusion hepatitis b vaccination of all nonimmune healthcare workers and measuring hbsab after vaccination can reduce the risk of nosocomial transmission of hbv to medical staff. furthermore, the risk of blood-borne disease transmission can be reduced by educating medical personnel on effective methods of reducing the risk of nssis as well as taking appropriate measures when nssis occur. resu...

conclusions epo resistance was negatively associated with anti-hbs levels and seroconversion. more studies are needed to highlight the underlying mechanisms regarding epo resistance and response to hbv vaccination in hd patients. results in total 97 patients were enrolled. for the entire group, stepwise linear regression analysis revealed that square root transformed anti-hbs levels were indepe...

background studies showed that hbv vaccination and consequent level of antibody are not completely adequate among dentists despite performance of highly exposure prone procedures. objectives the objectives of the study were to evaluate the levels of responsiveness to hbv vaccine and to determine the occupational factors associated among dental staff. materials and methods in total, 1612 dental ...

Chronic hepatitis B is still a major public health issue despite the successful prophylactic vaccination attempts.
