In Italy until sec. XIX, the beginning of vaccination duty allows to obtain some 
weighty aims in Public Health, like small pox eradication, polio and diphtheria 
elimination, or like the great reduction of tetanus and hepatitis B incidence. 
At the some, however, the vaccination duty doesn't allow to develop a 
"vaccination conscience" to do to accept the vaccines like the most important 
instrument, for effectiveness and utility, in the infectious diseases 
prevention. So, if from a side it's necessary to leave the vaccination duty from 
the another side it's necessary to make e leaded way of health education in the 
people and it's necessary to make a share of resources and aims in the sanitary 
world.
