The suggested dose of vitamin-A given at 9 months of age is–

Correct option is C

Sol. According to India's National Immunization Schedule, the first dose of Vitamin A (1 lakh IU) is given at 9 months of age along with the measles vaccine. It plays a crucial role in preventing childhood blindness and enhancing immunity. From 12 months onward, subsequent doses of 2 lakh IU are given every 6 months up to 5 years of age. Administering the wrong dose may lead to toxicity or inefficacy.
Explanation of each option:
· (a) 2 lakh IU – This is the standard dose given only after 12 months of age, every six months until the child turns five. Giving this high dose at 9 months may lead to side effects.
· (b) 3 lakh IU – This dose exceeds the recommended levels and can lead to hypervitaminosis A, which causes symptoms like vomiting, bulging fontanelle, or liver issues. It is not used in any age group under standard guidelines.
· (c) 1 lakh IU – Correct Answer. As per WHO and India's national guidelines, this is the first dose given at 9 months to strengthen immunity and prevent vitamin A deficiency.
· (d) 50,000 IU – This is below the therapeutic dose for any age in the immunization program. It is not sufficient to prevent vitamin A-related complications like xerophthalmia.
