title: Successful mass vaccination against hepatitis B virus in a hyperendemic area in Italy.
abstract: A pilot model of vaccination against hepatitis B virus suitable for mass vaccination was performed from 1983-1989 in the hyperendemic area of Afragola, a town of 60,000 inhabitants near Naples. In this area of high prevalence of HBsAg carriers, a consistent reduction in the incidence of hepatitis B virus infections as well as chronic related liver complications was observed.
