Childhood immunization coverage in zone 3 of Dhaka City: the challenge of reaching impoverished households in urban Bangladesh

Abstract

A household survey of 651 children aged 12-23 months in Zone 3 of Dhaka City carried out in 1995 revealed that 51% of them had fully completed the series of childhood immunizations. Immunization coverage in slum households was only half that in non-slum households. Apart from residence in a slum household, other characteristics strongly associated with the completion of the entire series of childhood immunizations included the following: educational level of the mother, number of children in the family household, mother's employment status, distance from the nearest immunization site, and number of home visits from family-planning field workers. The findings point to the need to improve childhood immunization promotion and service delivery among slum populations. Two promising strategies for improving coverage are to reduce the number of missed opportunities for immunization promotion during encounters between health workers and clients, and to identify through visits to households those children who need additional immunizations. In the long run, increasing the educational level of women will provide a strong stimulus for improving childhood immunization coverage in the population
