Note. 1. ATT estimates from PSM models using Epanechnikov kernel matching, PSM nearest neighbor matching, and PSM nearest neighbor matching with a caliper bandwidth of 0.005 and the common support condition imposed. The ATT represents the difference between the average outcome for those who received Rota various vaccine and their average outcome under the hypothetical scenario that they did not receive the Rotavirus vaccine in standard deviation units. After matching, treatment N = 34952 (666 unmatched) and control N = 44751 (1591 unused).

2. Control variables: Age of child, Sex of child, Birth order, Place of residence, Mother's schooling, Social group, Religion, Wealth quintile, Health and nutrition education (in PNC), Mother age at birth, Birth weight, Residing with husband/partner, Living with partner, Sanitation and Source of water.
