Immunization Coverage : Role of Sociodemographic Variables

Abstract EN

Children are considered fully immunized if they receive one dose of BCG, three doses of DPT and polio vaccine each, and one measles vaccine.

In India, only 44% of children aged 12–23 months are fully vaccinated and about 5% have not received any vaccination at all.

Even if national immunization coverage levels are sufficiently high to block disease transmission, pockets of susceptibility may act as potential reservoirs of infection.

This study was done to assess the immunization coverage in an urban slum area and determine various sociodemographic variables affecting the same.

A total of 210 children were selected from study population using WHO’s 30 cluster sampling method.

Coverage of BCG was found to be the highest (97.1%) while that of measles was the lowest.

The main reason for noncompliance was given as child’s illness at the time of scheduled vaccination followed by lack of knowledge regarding importance of immunization.

Low education status of mother, high birth order, and place of delivery were found to be positively associated with low vaccination coverage.

Regular IEC activities (group talks, role plays, posters, pamphlets, and competitions) should be conducted in the community to ensure that immunization will become a “felt need” of the mothers in the community.
