The figure of $0.25 refers to the cost of reaching one child with two doses of vitamin A through Operation 20/20. Two doses of vitamin A per year can alleviate vitamin A deficiency (VAD) in children under five who are at risk. This intervention has been proven to reduce overall child mortality by about 24%. $0.25 reflects the approximate cost for the purchase (as necessary) of the vitamins, logistics, transportation, and staff costs. Costs absorbed by our field partners are not included. Ultimately, no matter what the financial investment, as little at $0.25 can make a huge difference.
