In 1985-1986, 634 adult dialysis patients were tested prior to hepatitis B vaccination, representing 40% of the total patients in Latium, an Italian region. HBsAg and anti-HBs prevalences were 7.1 and 36.0%, respectively. Merck, Sharp & Dohme (MSD) and Pasteur plasma-derived vaccines were randomly allocated to the 44 dialysis units. An anti-HBs response greater than or equal to 10 IU/l was elicited in 58.5% of 236 subjects tested at 6 months, 63.4% MSD and 52.4% Pasteur (p n.s.). The relatively low response to the vaccine in this high-risk group stresses the need to improve the efficacy of the vaccination and to maintain policies of environmental control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
