Answer

**Step-by-Step Solution:**

1. **Understanding Vaccination**: Vaccination is a method used to protect individuals from infectious diseases. It involves the administration of a vaccine, which is a biological preparation.

2. **Definition of Vaccine**: A vaccine typically contains agents that resemble disease-causing microorganisms. These agents can be weakened or killed forms of the microbes, their toxins, or one of their surface proteins.

3. **Mechanism of Action**: When a vaccine is administered, it stimulates the immune system to recognize the agent as a threat. This leads to the activation of B lymphocytes.

4. **Production of Antibodies**: The primary role of B lymphocytes is to produce antibodies. Antibodies are proteins that specifically target and neutralize pathogens, providing immunity against the disease.

5. **Preventing Diseases**: By producing antibodies, vaccination helps the body to build a defense against specific diseases, making it an effective method for preventing infectious diseases.

6. **Historical Impact**: Vaccination has played a crucial role in the worldwide eradication of diseases, such as smallpox, demonstrating its effectiveness in providing immunity.

7. **Conclusion**: Therefore, vaccination protects a person from disease because it produces antibodies that help in fighting off the disease-causing agents.

**Final Answer**: Vaccination protects a person from disease because it produces antibodies.
