Vaccinations for kids

Hi, we are looking to move to Italy soon and I have a question about vaccinations. None of my kids are currently vaccinated. How strict are the Italians about vaccinations, how do they check this?

They have now been using computers so everything is recorded.  They do require the same vaccines as the US (except the chicken pox, but that is changing).  Other than the doctors nagging you to get the vaccines I have not so far seen the schools send children away for not getting them.

Thanks klvanzi, that is good to know.
