An Observational, Health Service Based Survey for Missed Opportunities for Immunization. Indian Pediatrics. 2011 August; 48(8): 633-636.http://imsear.searo.who.int/handle/123456789/168917Studies cite missed opportunities for immunization (MOI) as a contributor to undervaccination. The present prospective survey aimed at determining the magnitude of MOI, its contribution to under-vaccination, and identifying risk factors for MOI. Mothers of 1384 indoor patients 6 years were interviewed. There were 266 (19.2%) children with MOI, accounting for 79.6% of under-vaccination and 93% of under-vaccination time. MOI occurred significantly more often with home delivery (P <0.001, Odds ratio 5.1), incomplete or incorrect maternal knowledge of immunization (P=0.001, Odds ratio 4.8) and, general practice and non-Pediatric/ non- Medical college based practice (P=0.001, Odds ratio 4.0). The impact of sociodemographic factors on likelihood of MOI was not significant.enCausesIndiaMissedUnder-vaccinationOpportunitiesArticle
