Vitamin A Supplementation
MICS3 Data Analysis and Report Writing
Background
• It is estimated that 100-140 million children under five may be affected by vitamin A deficiency
• Vitamin A is essential for the functioning of the immune system. It reduces their risk of blindness, enhances their chances of survival, and reduces severity of childhood illnesses.
• Supplementing children aged six months to five years with two high-dose vitamin A capsules a year has been identified as a safe, cost-effective, efficient strategy for ending vitamin A deficiency.
International Goals & Targets
Virtual elimination of vitamin A
deficiency (VAD) and its consequences,
including blindness
