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

A recombinant vaccine is a vaccine produced through recombinant DNA technology. This involves inserting the DNA encoding an antigen (such as a bacterial surface protein) that stimulates an immune response into bacterial or mammalian cells, expressing the antigen in these cells and then purifying it from them.
eg- recombivax( protection against hepatitis b)
