One of the advantages of developing transgenic mice is that it is very useful:

Options

A. to study vaccine safety
B. in producing new varienties of mice
C. in developing a show piece example
D. in gene targeting

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Mice**: Transgenic mice are genetically modified organisms that have had a foreign gene deliberately inserted into their genome. This modification allows researchers to study the effects of specific genes and the processes they influence.

2. **Importance in Research**: Transgenic mice play a crucial role in biomedical research. They are used to model human diseases, test potential treatments, and study gene functions. Their genetic similarity to humans makes them valuable for understanding human health and disease.

3. **Testing Vaccine Safety**: One of the primary advantages of using transgenic mice is their utility in studying vaccine safety. Before a vaccine can be approved for human use, it must undergo rigorous testing to ensure it is safe and effective.

4. **Regulatory Requirements**: Regulatory agencies require that new vaccines and drugs be tested in animal models before they can be tested in humans. Transgenic mice provide a suitable model for this testing, allowing researchers to observe how the vaccine interacts with the immune system.

5. **Faster Results**: Using transgenic mice allows researchers to obtain results more quickly than traditional methods. This efficiency is crucial in the development of new vaccines and therapies, especially during public health emergencies.

6. **Conclusion**: Given the advantages outlined, the correct answer to the question is that one of the advantages of developing transgenic mice is that they are very useful to study vaccine safety.

**Final Answer**: To study vaccine safety.
