First generation vaccines carry the live, 'damaged' or dead entire organism. They impart immunity by inducing the antibody immune response and the immune resposes entailing killer and helper T-cells. Since the attenuated vaccines can still turn into the toxic form and could cause disease; the second generation vaccines were developed which are made up of protein antigens or recombinant proteins and function by inducing antibody responses, but not killer T cell responses. The third generation vaccines are the DNA vaccines which have a round small modified bacterial DNA and release one or more particular antigens. The Hepatitis B and Herpes virus vaccines carry hepatitis B surface antigen and thus are the second generation vaccines.
