Introduction:

Childhood immunization promotes child survival and provides opportunities for children to thrive.On
thecontrary to expectation of 90% childhood vaccination coverage, the DLHS-4 (2012-2013) survey
showed significantly low childhood vaccination coverage of the Tamilnadu state 56.2% and Coimbatore
district 50%. Hence, Coimbatore was one among the 8 districts that were included in Mission Indradhanush
phase1. It is important to do a periodic estimation of vaccination coverage to monitor the forward
movement in the provision of immunization services. This study aims to estimate the current vaccination
coverage and to identify the factors influencing incomplete /non-vaccination among children aged 12-23
months in a rural block- Thondamuthur, Coimbatore, Tamilnadu.
Methodology:

A cross-sectional survey was conducted among the children aged 12-23 months, residing in the
rural block Thondamuthur that covers the service area of RHTC. Using cluster sampling technique,36
clusters were selected as suggested by the updated reference manual - Vaccination coverage by cluster
survey 2015 and 205 households were visited in each cluster and all eligible children were included
in the study. A total of 254 children were included in the study after visiting 7380 households. A
survey questionnaire of vaccination was used for data collection. After obtaining the ethical clearance,
the information about vaccination status of the child was collected from the care taker and the home-
based record available at home.

Results:
The current vaccination coverage among the children aged 12-23 months in the rural block –
Thondamuthur, Coimbatore was estimated as 78.3% (95% CI 70.7 – 85.9). Mother’s education (AOR:
5.3) and house type (AOR: 3.4) showed significant association with partial or non-vaccination status of
the child. The coverage of the conventional vaccines among the same children was 85% (95% CI 77-93).
Discussion:

The coverage of fully vaccinated children of this study is better than DLHS-4 (2012-2013) coverage
(50%) and the study conducted by ICMR – NIE, Chennai (2015) by Murhekaret al. (79.9%). However
achieving a vaccination coverage level based on the knowledge on basic reproduction number (R0) and
Herd immunity threshold values of each vaccine preventable disease will help to improve the vaccination
coverage and strengthen the Programme.
