What is the IAP recommendation for varicella vaccination in a healthy 15-month-old child?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Two doses, with the second at least 3 months after the first

IAP recommends two doses of live varicella vaccine, the first from 15 months and the second at least 3 months later (some give it at 4 to 6 years). Two doses give better protection and reduce breakthrough disease. Pregnancy and immunodeficiency are contraindications.
