Assessing vaccination coverage in infants- survey studies versus the Flemish immunisation register: achieving the best of both worlds.

Infant immunisation coverage in Flanders- Belgium- is monitored through repeated coverage surveys. With the increased use of Vaccinnet- the web-based ordering system for vaccines in Flanders set up in 2004 and linked to an immunisation register- this database could become an alternative to quickly estimate vaccination coverage. To evaluate its current accuracy- coverage estimates generated from Vaccinnet alone were compared with estimates from the most recent survey (2012) that combined interview data with data from Vaccinnet and medical files. Coverage rates from registrations in Vaccinnet were systematically lower than the corresponding estimates obtained through the survey (mean difference 7.7%). This difference increased by dose number for vaccines that require multiple doses. Differences in administration date between the two sources were observed for 3.8-8.2% of registered doses. Underparticipation in Vaccinnet thus significantly impacts on the register-based immunisation coverage estimates- amplified b
