Children of age 24- 47 months were selected using systematic random sampling. Information on socio- demographic factors and immunization status was obtained by house- to- house visit. Immunization coverage of all vaccines was computed and analysis of association between immunization coverage and socio- demographic factors was done. Results. The coverage levels were 82.7% for BCG, 81.5% for DPT/ OPV 1, 76.8% for DPT/ OPV 2, 70.7% for DPT/ OPV 3 and 65.3% for measles vaccine. It was 41.4% and 41.6% for DPT booster and MMR vaccine. Higher education of mother ( OR= 1.96) and father ( OR= 1.80), father's occupation ( OR= 1.86), residential status ( OR= 1.76), place of birth ( OR= 2.64) and presence of immunization card ( OR= 5.8) were significant determinants for complete immunization on univariate analysis. On regression analysis mother's education ( OR= 1.43), presence of immunization card OR= 2.05 and place of birth ( OR= 3.80) remained significant. Conclusion. Immunization evaluation surveys have shown a wide variation across regions, states and differrent strata of the society.
