Summaryobjectives To measure the accuracy and quality of immunization information systems in a range of low-income countries eligible to receive GAVI support. results Almost half of countries obtained a VF below 80% and only nine showed consistently high VF and QS scores. The most frequent weaknesses in the information systems were inconsistency of denominators used to estimate coverage, poor availability of guidelines (e.g. for late reporting), incorrect estimations of vaccine wastage and lack of feedback on immunization performance. In all six countries that failed a first DQA and undertook a second DQA, the VF and all QSs improved, not all of them statistically significantly.conclusions The DQA is a diagnostic tool to reveal a number of crucial problems that affect the quality of immunization data in all tiers of the health system. It identifies good performance at HU and district levels which can be used as examples of best practices. The DQA methodology brings data quality issues to the top of the agenda to improve the monitoring of immunization coverage.
