title: [A rapid evaluation of vaccination coverage in Bogotá, 2006].
abstract: OBJECTIVE
  Evaluating vaccination coverage in the infant population aged 0-23 months by cluster (locality) in Bogotá and identifying reasons for the lack of vaccination coverage.
  
  
  METHODS
  This was a descriptive, retrospective study. Sample size was calculated on target population (children aged 0-23 months), further divided into 0-1, 2-6, 7-11 and 12-23 month sub-groups by tri-stage sampling to ascertain newborn vaccination status, evaluate opportune oral polio vaccine (OPV) and pentavalent vaccine third dose vaccination and opportune measles, mumps and rubella (MMR) vaccination.
  
  
  RESULTS
  5,845 children were surveyed; 96.7% had immunisation cards, 75.3% were registered in the Social Protection System and 12.6% (713 out of 5,845) had not been vaccinated. Vaccination coverage by biological products was as follows: 99.1% BCG, 93.0% pentavalent vaccine, 93.2% OPV, 85% MMR. Vaccination opportunity was 5,328 for BCG (94.3%), 1 256 for OPV (88.6%), 1 112 for pentavalent (88.5%) and 1,702 for MMR (69.5%) with 33 vaccination errors (1.3%). Among the identified reasons for non-vaccination were confused health service logistics and coordination (59.2%), misguided parental beliefs (27.9%) and unregistered children (12.8%).
  
  
  CONCLUSIONS
  Useful and timely vaccine coverage was evident with BCG; there were difficulties regarding recording pentavalent vaccination. Information, education and mass communication strategies must be developed to counteract reasons given for non-vaccination and to educate parents and tutors in its opportune application to increase triple-viral vaccine coverage.
