Immunization in India’s Universal Immunization Program improves schooling attainment and economic status for women
In an analysis of the impact of India’s Universal Immunization Program (UIP) on schooling attainment in adults, a subgroup analysis found a strong positive association between UIP implementation and increased school attainment for women. Women born after the UIP rollout attained 0.29 more schooling grades compared women from the same household born before UIP rollout. Among unmarried women, the UIP was associated with an increment of 1.2 schooling years, which corresponds to as much as an INR 35 (US $0.60) increase in daily wages. Thus, the researchers concluded that the UIP is also likely to improve the economic status of women in India.

Children of mothers with no education or primary education are more likely to have delayed vaccinations
A study of delayed vaccination in India found that children whose mothers had no formal education were 37-81% more likely to have delayed vaccinations than children of mothers with 12 or more years of schooling [depending on the vaccine]. Children whose mothers had a primary school eduction fared only slightly better with 33-62% greater odds of getting their vaccination late, when compared to those with highly educated mothers.
Data in this analysis was from the National Family and Health Survey 4.

Children in communities with higher literacy rates are more likely to be fully immunized
Nigerian Demographic Health Survey data suggests that community literacy influences immunization status. Children in communities with low levels of illiteracy were 82% less likely to be fully immunized than children in communities with medium levels of illiteracy.
