abstract: OBJECTIVE
  Is LQAS technique better than cluster sampling technique in terms of resources to evaluate the immunization coverage in an urban area?
  
  
  OBJECTIVE
  To assess and compare the lot quality assurance sampling against cluster sampling in the evaluation of primary immunization coverage.
  
  
  METHODS
  Population-based cross-sectional study.
  
  
  METHODS
  Areas under Mathikere Urban Health Center.
  
  
  METHODS
  Children aged 12 months to 23 months.
  
  
  METHODS
  220 in cluster sampling, 76 in lot quality assurance sampling.
  
  
  METHODS
  Percentages and Proportions, Chi square Test.
  
  
  RESULTS
  (1) Using cluster sampling, the percentage of completely immunized, partially immunized and unimmunized children were 84.09%, 14.09% and 1.82%, respectively. With lot quality assurance sampling, it was 92.11%, 6.58% and 1.31%, respectively. (2) Immunization coverage levels as evaluated by cluster sampling technique were not statistically different from the coverage value as obtained by lot quality assurance sampling techniques. Considering the time and resources required, it was found that lot quality assurance sampling is a better technique in evaluating the primary immunization coverage in urban area.
