Actual immunization coverage throughout Europe: are existing data sufficient?


Assessing vaccine coverage is an essential component of vaccine programme monitoring and evaluation. Vaccine coverage data are available in EU/EEA countries at both national and subnational levels and are used for programmatic purposes at any level. European-wide data collection is performed by WHO through the Centralized Information System for Infectious Diseases- as part of the global data collection jointly conducted with UNICEF. Data quality and comparability are still challenging at an international level. According to available information- vaccination registries are available in 11 countries in the EU/EEA- but only in five countries do they have national coverage. In 2012 ECDC- through the VENICE II network- started the European Vaccination Coverage Collection System (EVACO project)- with the final aim of improving the quality of vaccine coverage data at EU level- by defining and implementing standards.
