What are recombinant DNA vaccines? Give two examples of such vaccines. Discuss their advantages.

Explanation

### Step-by-Step Solution:

**Step 1: Define Recombinant DNA Vaccines**
Recombinant DNA vaccines are a type of vaccine created using recombinant DNA technology. This technology allows scientists to combine DNA from different sources, specifically the gene of interest from a pathogen (like a virus or bacterium) with a vector (often a harmless virus or plasmid). This process results in a vaccine that can stimulate an immune response without causing the disease.

**Step 2: Provide Examples of Recombinant DNA Vaccines**
Two well-known examples of recombinant DNA vaccines are:
1. **Hepatitis B Vaccine** - This vaccine is produced using a yeast cell that has been genetically modified to produce a protein from the Hepatitis B virus. When administered, it prompts the immune system to recognize and fight the actual virus if encountered.
