Vitamin A supplementation: who, when and how

Vitamin A supplements for young children aged 6–59 months The World Health Organization (WHO) recommends that all children aged 6–59 months should receive supplements if they live in a community where VAD is a public health problem. These are communities where the prevalence of night blindness is ≥ 1% in children aged 24–59 months, or where the prevalence of VAD is ≥ 20% in infants and children aged 6–59 months. The suggested vitamin A supplementation scheme for prevention of deficiency in children aged 6–59 months in areas where VAD is a severe public health problem is shown in Table 1.
