Background: Infectious diseases are a major cause of morbidity and mortality in children. One of the most cost-effective and easy methods for child survival is immunization. The objective of study was to assess the immunization coverage in the rural area of Dhule.

Methods: A community based cross-sectional study was conducted by using WHO 30x7 cluster sampling technique in Primary Health Centre, Kheda catchment villages among children aged 12-23 months on the day of survey. The total sample size was found out to be 210. Identification of clusters was done as per WHO manual on 30×7 cluster survey. Interviews were conducted as per a structured interview format in households with eligible children. Data feeding was done in MS Excel sheet.

Results: Full immunization coverage (FIC) was found out to be 58.6%. Drop-out rate was calculated to be 22.95%. The main reason for not completing the immunization was unaware to return for subsequent vaccine doses.

Conclusions: Coverage evaluation of vaccines was found out to be 58.6%. Drop-out rate is high.
