Objectives: We described the results from the Swiss National Vaccination Coverage Survey (SNVCS) 2005-2007, a survey designed to monitor immunization coverage of children and adolescents residing in Switzerland in each canton within a three-year period.
Methods: The SNVCS is a cross-sectional survey using a two-stage sampling design targeting children aged 2, 8, and 16 years. Families of selected children were contacted by mail and telephone.
