## **Core Concept**
The Indradhanush mission is a health mission of the government of India that aims to immunize all children under the age of 2 years, as well as pregnant women, against seven vaccine-preventable diseases. The vaccines included in this mission target diseases such as diphtheria, whooping cough, tetanus, poliomyelitis, tuberculosis, measles, and Hepatitis B.

## **Why the Correct Answer is Right**
The Indradhanush mission includes vaccines for DPT (diphtheria, pertussis, and tetanus), Polio (both Oral Poliovirus Vaccine and Inactivated Poliovirus Vaccine), BCG (Bacillus Calmette-Guérin for tuberculosis), Measles-Rubella (MR), and Hepatitis B. The mission specifically targets to immunize against these diseases. Without the specific options provided, it's challenging to directly state why a particular vaccine is not included. However, generally, vaccines like those for Japanese Encephalitis, Haemophilus influenzae type b (Hib), and Rotavirus are also part of the expanded program but might not be universally included in the basic package for all states or regions.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it is part of the Indradhanush mission (though the specific vaccine isn't mentioned).
- **Option B:** Similarly, this is incorrect as it is included (specifics depend on the vaccine).
- **Option D:** This too is incorrect as it is part of the mission.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the Indradhanush mission focuses on immunizing against major vaccine-preventable diseases. It's essential to recall that vaccines under this mission are strategically selected based on disease prevalence, impact on mortality, and feasibility of vaccine delivery.
