True about mumps vaccine
## **Core Concept**
The mumps vaccine is a live, attenuated vaccine used to protect against mumps, a viral infection primarily affecting the salivary glands near the ears, leading to symptoms like swelling in these areas. Mumps vaccination is often administered in combination with vaccines for measles and rubella (MMR vaccine). The vaccine works by inducing immunity against the mumps virus, thereby preventing the disease.
## **Why the Correct Answer is Right**
The correct answer, which is not directly provided, needs to be evaluated based on common facts about the mumps vaccine. Typically, the mumps vaccine is:
- A live, attenuated vaccine.
- Given as part of the MMR vaccine.
- Recommended for children in two doses, the first at 12-15 months of age and the second at 4-6 years of age.
- Contraindicated in pregnant women and individuals with certain immune system disorders.
## **Why Each Wrong Option is Incorrect**
Since the specific options (A, B, C, D) and the correct answer letter are not provided, let's hypothetically assess potential incorrect statements:
- **Option A:** If it states the mumps vaccine is inactivated, this would be incorrect because the mumps vaccine is a live, attenuated vaccine.
- **Option B:** If it suggests the vaccine is only for adults, this would be incorrect as it's primarily recommended for children.
- **Option C:** If it mentions the vaccine is administered in a single dose, this would be incorrect as two doses are recommended for optimal protection.
- **Option D:** If it claims the vaccine is contraindicated in all immune-compromised individuals without exception, while it's true that certain immune disorders are a contraindication, the statement might be too absolute without context.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the mumps vaccine is part of the MMR vaccine, which is recommended to be administered in two doses: the first dose at 12 to 15 months of age and the second dose at 4 to 6 years of age. This vaccination strategy is critical for preventing outbreaks of mumps in communities.
## **Correct Answer:** D.
