In Italy systematic mandatory tetanus immunization of children started in 1968.
In a national sample of 241 young males born after 1968 the prevalence of non-immune subjects was 11.2% (5.5% in the North-Centre, 15.9% in the South-Islands; p<0.02).
Comparing these data with the corresponding figure obtained in a previous study of subjects born before 1968 a significant decrease (11.2% versus 32.6%; p<0.01) is observed.
The prevalence of non-immune subjects born after 1968 is significantly (p<0.01) lower than that observed in subjects born before 1968 by geographical area as well as by area (urban/rural) of residence.
