Overview and assessment of available data sources to determine incidence of vaccine preventable diseases- vaccination coverage- and immune status in Germany.
The surveillance of vaccine preventable diseases and vaccination coverage is necessary in order to deliver epidemiological data with respect to national vaccination recommendations and control targets. The data available on the incidence of vaccine preventable diseases- vaccination coverage- and immune status of the population are fragmentary and do not allow the epidemiological situation to be fully assessed. Although the majority of vaccine preventable diseases are under surveillance nationwide (by statutory reporting or sentinel surveillance)- data are not available for some diseases. In addition- data on vaccination coverage are not collected centrally. Nationwide data on vaccination coverage are only available for children at school entry. Use of secondary data such as data from health insurance companies or associations of statutory health insurance physicians provides an opportunity to close gaps in knowledge and to improve the surveillance of vaccine preventable diseases.
