Immunization Analysis and Insights
The Immunization Analysis & Insights Unit is a data hub and analytics engine for immunization data and performs analytics. The unit supports the work of other technical units within the department of Immunization, Vaccines and Biologicals (IVB) and drives innovation in data quality and use in countries. It also has responsibility for IVB’s global work on VPD surveillance and generating data and evidence on the public health and economic impact of vaccines.

Data Quality Self-assessment

The Data Quality Self-assessment (DQS) is a flexible toolbox of methods used to evaluate different aspects of the immunization monitoring system at district and health unit (HU) levels

It is designed by and for staff collecting and using immunization data at national, provincial or district levels. It aims to assist countries in diagnosing problems relating to data collection and providing orientation to improve district monitoring as highlighted in the Reaching Every District (RED) approach

The DQS aims to determine :

  • the accuracy of reported figures for coverage (i.e. number of immunizations) and for any other immunization system indicator
  • the quality of any component of the immunization monitoring system

The assessment includes a review of data accuracy at different levels and a self-designed questionnaire reviewing monitoring quality issues (e.g. availability of vaccination cards, use of tally sheets, directly-observed recording and reporting practices). Data are then analysed, with a view to identifying strengths and weaknesses which need to be corrected
