Answer

Vaccination programs implemented in highly endemic areas seem to have reduced the prevalence of HBV infection. In Taiwan, for example, HBV seroprevalence declined from 10% in 1984 (before vaccination programs) to less than 1% in 1994 after the implementation of vaccination programs, and the incidence of HCC declined from 0.52% to 0.13% during the same period.
