Answer

To answer the question "Immunity acquired after an infection is ________ immunity," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Immunity**: Immunity refers to the body's ability to resist and fight off infections caused by pathogens such as bacteria and viruses.

2. **Types of Immunity**: There are several types of immunity:
- **Artificially Acquired Immunity**: This type is induced through vaccinations, where a vaccine containing antigens stimulates the immune response without causing the disease.
- **Passive Immunity**: This occurs when readymade antibodies are given to a person, providing immediate protection without the body producing its own antibodies.
- **Innate Immunity**: This is the natural defense mechanism present at birth, including physical barriers like skin and internal defenses like stomach acid.
- **Natural Acquired Immunity**: This type develops when a person is exposed to a live pathogen, leading to the development of the disease and subsequent immunity.

3. **Identifying the Correct Type**: The question specifically asks for immunity acquired after an infection.
- Since natural acquired immunity occurs when a person is exposed to a live pathogen and develops the disease, this is the type of immunity that is acquired after an infection.

4. **Conclusion**: Therefore, the correct answer is "Natural Acquired Immunity."

### Final Answer:
Immunity acquired after an infection is **Natural Acquired Immunity**.
