What are recombinant DNA vaccines? Give two examples of such vaccines. Discuss their advantages.
Recombinant vaccines are made up of a small circular DNA (plasmid) that has very tiny piece of pathogen DNA incorporated in it to produce one or two specific proteins of the pathogen.
This recombinant DNA is introduced in to the bacteria or yeast cells, where it can use cell’s machinery to produce polypeptides of the pathogen. These are used as vaccine to trigger a range of immune responses. Vaccine produced by using this approach allow large scale production, e.g.
