Update on hepatitis B vaccination in Italy 10 years after its implementation / A.R. Zanetti. - In: VACCINE. - ISSN 0264-410X. - 19:17-19(2001 Mar 21), pp. 2380-2383.
Abstract:
Since the beginning of the Italian program of immunization against hepatitis B, vaccine has been given to more than 9 million children, with an outstanding record of safety and efficacy. The coverage rate is globally around 94%, with differences between Northern and Southern regions, the latter having the lower acceptance rate. According to the National Surveillance System (SEIEVA), the incidence of acute hepatitis B per10(5) inhabitants declined from 5.4 in 1990 to 2.9 in 1998. The reduction was even greater among 15-24-year-old individuals, where the incidence rate per 10(5) decreased from 17.3 to 4.2 in the same period. In parallel with the decline of hepatitis B, Delta hepatitis has also dropped significantly. We expect that by the year 2003 (12 years after the beginning of the program) this vaccination strategy will have led to the protection of all Italians aged 0-24 years, who are those at the higher risk for acquiring hepatitis B virus (HBV) and for developing the chronic carrier state.
