[Vaccination of children and their parents' attitude in a Swiss town (author's transl)].

A large group of school-children 6-10 years of age were checked for their immunization status and by questionnaire for their parent's attitude to vaccinations. Children of higher socio-economic status have better immunization protection. In spite of pretended high motivation, people from Southern countries have a significantly smaller percentage of immunized children than Swiss people. This is probably caused by insufficient information.
