Solution
Recombinant DNA vaccine:
In recombinant DNA vaccines, the antigens are not directly injected into the body.
Instead the rDNA containing the gene for coding the antigen in a vector is incorporated into the body.
The gene produces antigens inside the body and the immune responses are elicited for that antigen.
Then the memory of the antigen is retained by the immune system.
Pictorial representation of rDNA vaccine:
