The concerted action is aimed at comparing different aspects which are integral components of immunization programmes and defined as 3 subprojects:
Quality assurance of coverage assessment
Outbreak investigation of target diseases
Monitoring of adverse events following immunization.
Some European countries already have reasonably good methods for evaluation of their immunization programmes but there is currently a diversity of the systems and few comparable data. Research in comparing their techniques and studying their reproducibility should be helpful to increase the probability of reaching immunization targets.
This project originated in the view of the objectives of elimination of some immunizable diseases which were agreed upon during WHO meetings of European EPI managers.
