Under NIS, total dose of Vit A given to a child is:
|A||5 lac IU|
|B||6 lac IU|
|C||9 lac IU|
|D||17 lac IU|
The strategy is to administer a single massive dose of 200,000 IU of vitamin A in oil (retinol palmitate) orally every 6 months to preschool children (1 year to 5 years), and half that dose (100,000 IU) to children between 6 months and one year of age, thus making a total of 17 lac IU.
