Background: High levels of immunization coverage in children can ensure the control of vaccine-preventable diseases, and there are various factors that can affect preschool immunization. Studies that focus on vaccination coverage in various populations are crucial for identifying the vaccination status of a given community and for strategizing the national programs. This study assessed the vaccination coverage in preschool children living in a resettlement colony in an area of New Delhi.

Methods: This community-based cross-sectional study was conducted in JJ Colony, Madanpur Khadar Extension of South Delhi, New Delhi between October 2008 to January 2009, in 100 preschool children between 24 – 47 months of age, with equal number in both genders. No significant association of the vaccination status with factors like gender of the children, educational, or socio-economic condition, was found in this study.

Results: Out of a total of 100 children studied, forty-four children (44%) were fully vaccinated, forty-nine children (49%) were partially immunised, and seven children (7%) were not vaccinated. Vaccines for diphtheria-tetanus-pertussis (DPT-I) and oral poliovirus vaccine (OPV-I) had the maximum coverage (92%) while DPT Booster and OPV Booster had the lowest (44%).

Conclusion: Future possibilities and potential for evaluating vaccination coverage should be explored in vulnerable areas like resettlement colonies, in migrant populations and in urban poor sections of society to get estimates on the gap in vaccination coverage in such areas.
