Explanation

The National Immunization Schedule (NIS) of India recommends a two-dose schedule for the Measles-Rubella (MR) or MMR vaccine to ensure adequate immunity.
The first dose is administered between 9 and 12 months of age.
The second dose is administered between 16 and 24 months of age.
The option '15 to 18 months' is the best fit among the choices provided, as it aligns with the window for the second dose of the MMR vaccine.

Option B: This age range is immediately after the window for the first dose (9-12 months) and is too early for the second dose (16-24 months).
Option C: This age range (24-36 months) is outside the recommended window for the second dose, which should be completed by 24 months.
Option D: This is well beyond the recommended age for the second dose in the NIS. While the IAP recommends a third dose at 4-6 years, this is not part of the national schedule.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The question tests the knowledge of the National Immunization Schedule (NIS) in India, specifically the timing of the MMR vaccine administration as background academic context rather than a clinical decision trigger.
Understanding the correct immunization schedule is critical for nurses to ensure children receive timely vaccinations, preventing outbreaks of vaccine-preventable diseases like measles, mumps, and rubella.
The two-dose MR/MMR strategy is crucial for achieving herd immunity and supports India's national goal of measles and rubella elimination.
What if a child misses the second dose at 16-24 months? The nurse should advise the parents to get the child vaccinated as soon as possible. The vaccine can be given up to 5 years of age.

How to Approach the Question

First, identify the key phrase in the question: 'National Immunization Schedule'. This indicates that a specific, official schedule is being referenced, not a general or international one.
Recall the two-dose schedule for the MR/MMR vaccine in India: the first dose at 9-12 months and the second dose at 16-24 months.
Examine the given options to see which one fits the schedule.
Notice that the window for the first dose (9-12 months) is not an option.
Deduce that the question is likely asking about the second dose.
Select the option '15 to 18 months' as it is the only choice that aligns with the second dose window of 16-24 months.
