Over the past decade several studies have examined the effect of vitamin A on reducing mortality among children aged ≥6months at the time of intervention. Impact of vitamin A supplementation can significantly reduce total mortality but it is only established through supplementation programs in children age 6 months or older. It was assumed that breast milk protects infants from vitamin A deficiency, but recent evidence has challenged this. Infants born with low stores of vitamin A and if the mother breast milk has a low concentration of vitamin A, as found in developing countries, the infants might be unable to meet their daily requirements and improve body reserves. There is association between mortality and degree of vitamin A deficiency, greater the degree of deficiency, higher the mortality.
