Factors Associated with Incomplete Childhood Immunization in Oshodi-Isolo District of Lagos State South West Nigeria


Immunization against childhood diseases such as tuberculosis, poliomyelitis, measles, diphtheria, whooping cough and tetanus reduce childhood morbidity and mortality. Studies have shown that the cost to treat a vaccine preventable disease may be up to 30-times more than the cost of the vaccine, children who contract these preventable diseases usually suffer from impaired physical growth, cognitive development, emotional development, and social skills.

The prevention of child mortality through immunization is one of the most cost-effective and widely applied public health interventions, Immunization is one of the most effective, safest and efficient public health interventions as it is estimated to save at least 3 million lives from vaccine preventable diseases.

Despite the significant decline in the incidence of vaccine-preventable diseases as a result of increased vaccination coverage worldwide, there are many children with delayed and incomplete vaccination.
