Key Concept

Key Evidence: In the mid-1980s, the Indian government examined the effect of their universal immunization program on child mortality and educational attainment. Results indicate that exposure to the program reduced infant mortality by 0.4 percentage points and under five child mortality by 0.5 percentage points. These effects on mortality account for approximately one-fifth of the decline in infant and under five child mortality rates between 1985-1990. The effects are more pronounced in rural areas, for poor people, and for members of historically disadvantaged groups.
