Vaccine is included in

Options

A. Natural passive acquired immunity
B. natural active acquired immunity
C. artifical active acquired immunity
D. artificial passive acquired immunity

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the category in which vaccines are included. We need to analyze the provided options to identify the correct classification.

2. **Analyzing the Options:**
- **Option A: Natural Passive Acquired Immunity**
- Definition: Immunity gained naturally without exerting energy, often from the mother (e.g., through breast milk).
- Conclusion: This is not the correct option for vaccines, as vaccines are not naturally acquired.

- **Option B: Natural Active Acquired Immunity**
- Definition: Immunity gained naturally through exposure to pathogens, where the body actively responds to create immunity (e.g., recovering from a disease).
- Conclusion: This is also not the correct option for vaccines, as vaccines are not acquired through natural exposure.

- **Option C: Artificial Active Acquired Immunity**
- Definition: Immunity that is artificially induced (man-made) and requires the body to actively respond to create immunity (e.g., through vaccination).
- Conclusion: This is the correct option for vaccines, as they are designed to stimulate an active immune response.

- **Option D: Artificial Passive Acquired Immunity**
- Definition: Immunity that is artificially provided without the body exerting energy (e.g., through injections of antibodies).
- Conclusion: This is not the correct option for vaccines, as vaccines promote active immunity rather than passive immunity.

3. **Final Conclusion:**
Based on the analysis of the options, the correct answer is **Option C: Artificial Active Acquired Immunity**. Vaccines are included in this category because they are man-made and stimulate the body to actively create immunity.
