Study Network

Data sources

The VAC4EU members have access to a large variety of electronic health care databases in different EU countries. Electronic health care databases are usually a result of the electronic recording of routine health care and are not developed specifically for research.

The structure and content vary within and between European countries. Data may arrive from general practitioners, claims data, vaccine registries, surveillance data, trial data or a combination of those. This heterogeneity requires thorough assessment of the characteristics, data content indicators whether data are fit-for purpose.

Databases that have been characterised during the ADVANCE project are:


A meta-data survey was created to identify available data sources

Meta-data are collected about the type of variables, provenance, access procedures and validation/publications. Since meta-data need to be updated regularly in VAC4EU we will rely on the ENCePP data sources registry and ask members to record their data in this registry.
