MORON-DUARTE, Lina  and  ESPITIA, María T. A rapid evaluation of vaccination coverage in Bogotá, 2006. Rev. salud pública [online]. 2009, vol.11, n.2, pp.237-246. ISSN 0124-0064.

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. Materials and 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.
