**Core Concept**
Mission Indradhanush is a vaccination program launched by the Government of India in 2014 to immunize all children under the age of 2 years and pregnant women against seven vaccine-preventable diseases. The program aims to cover all children and pregnant women across the country, focusing on the 100 high-focus districts.

**Why the Correct Answer is Right**
The vaccines included under Mission Indradhanush are BCG (Bacille Calmette-Guérin) for tuberculosis, DPT (diphtheria, pertussis, and tetanus) for diphtheria, pertussis, and tetanus, Hepatitis B for hepatitis B, Measles for measles, and Rubella for rubella. Japanese Encephalitis vaccine is also included in the program as a supplement. However, Typhoid vaccine is not a part of the Mission Indradhanush program, as it is not one of the seven vaccine-preventable diseases targeted by the initiative.

**Why Each Wrong Option is Incorrect**
**Option A:** BCG is included in the Mission Indradhanush program to protect against tuberculosis.
**Option B:** Japanese Encephalitis vaccine is also included in the program as a supplement to protect against Japanese encephalitis.
**Option D:** Measles vaccine is included in the program to protect against measles.

**Clinical Pearl / High-Yield Fact**
The Mission Indradhanush program has led to significant improvements in immunization coverage across India, with a focus on reaching underserved populations, especially in the 100 high-focus districts. This program serves as a model for other countries to improve vaccination coverage and reduce vaccine-preventable diseases.

**✓ Correct Answer: C. Typhoid**
