title: [Polio vaccination failure in Italy, years 2006-2010].
abstract: OBJECTIVE
  The purpose of this paper is to describe the lack of antipolio vaccination and its reasons, in the period 2006-2010. STUDY DESIGN, SETTING AND PARTICIPANTS. Until 2014 the data on vaccination activities, aggregated at the regional level, were sent to the Ministry of Health using a paper form used to collect the data and then to calculate vaccine coverage (CV) at 24 months. This form contains a section for identifying the reasons for polio vaccination failure.
  
  
  RESULTS
  During the reporting period the national CV was always above 95%. The highest rates of non-vaccination were always observed in the same Region. Polio vaccination failure is well explained in 82%of cases, but only three Regions have always provided an explanation, while two have extremely low percentages of explanation, less than 50%. The dominant mode is «noncompliant » (45.5%), followed by «undetectable» (26.5%).
  
  
  CONCLUSIONS
  The percentage of explanation of non-vaccination was lower than expected. At the moment we cannot clarify why, but only speculate that the lack of a computerized immunization registry has been a key element. Probably, the form used was not sufficiently detailed to monitor the phenomenon of non-vaccination and program interventions. Updating the form, in 2013, we took into account these and other critical issues.
