AB  - Inadequate evaluation of vaccine coverage after mass vaccination campaigns, such 
      as used in national measles control programmes, can lead to inappropriate public 
      health responses. Overestimation of vaccination coverage may leave populations at 
      risk, whilst underestimation can lead to unnecessary catch-up campaigns. The 
      problem is more complex in large urban areas where vaccination coverage may be 
      heterogeneous and the programme may have to be fine-tuned at the level of 
      geographic subunits. Lack of accurate population figures in many contexts further 
      complicates accurate vaccination coverage estimates. During the evaluation of a 
      mass vaccination campaign carried out in N'Djamena, the capital of Chad, Lot 
      Quality Assurance Sampling was used to estimate vaccination coverage. Using this 
      method, vaccination coverage could be evaluated within smaller geographic areas 
      of the city as well as for the entire city. Despite the lack of accurate 
      population data by neighbourhood, the results of the survey showed heterogeneity 
      of vaccination coverage within the city. These differences would not have been 
      identified using a more traditional method. The results can be used to target 
      areas of low vaccination coverage during follow-up vaccination activities.
