Following vaccine has been produced from yeast by recombinant DNA technology

Options

A. Hepatitis A
B. Hepatitis B
C. Hib
D. Oral Polio

Answer

**Step-by-Step Text Solution:**

1. **Understanding Recombinant DNA Technology**:
- Recombinant DNA technology involves the insertion of DNA from one organism into the DNA of another organism to create a new genetic combination. This technology is used to produce various biological products, including vaccines.

2. **Traditional Vaccines vs. Recombinant Vaccines**:
- Traditional vaccines often involve using killed or attenuated (weakened) forms of pathogens to stimulate an immune response. In contrast, recombinant vaccines utilize genetic engineering to produce antigens that can elicit an immune response without using the live pathogen.

3. **Identifying the Vaccine Produced from Yeast**:
- The question specifically asks for a vaccine produced from yeast using recombinant DNA technology. The hepatitis B vaccine is a prime example of this. It is produced by inserting the DNA that codes for the hepatitis B virus surface antigen into yeast cells, which then produce the antigen.

4. **Evaluating Other Options**:
- The other vaccines mentioned, such as the hepatitis A vaccine, HIV vaccine, Hib vaccine, and oral polio vaccine, do not utilize recombinant DNA technology in their production. Hepatitis A uses killed microbes, HIV and Hib vaccines are not produced using recombinant methods, and the oral polio vaccine uses attenuated forms.

5. **Conclusion**:
- Therefore, the vaccine produced from yeast by recombinant DNA technology is the **Hepatitis B vaccine**.

**Final Answer**: The vaccine produced from yeast by recombinant DNA technology is the **Hepatitis B vaccine**.
