OBJECTIVE: To assess the immunization coverage of BCG, DPT, OPV, Measles, MMR and Hepatitis B vaccines in two urbanized villages of East Delhi and study the factors affecting the coverage. METHODS: 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 different strata of the society.
