Abstract:
Studies cite missed opportunities for immunization (MOI) as a contributor to under-vaccination. 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.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
