title: Vaccine design: future possibilities and potentials.
abstract: Recent developments in the understanding of the structure and replications of a wide range of pathogens, including viruses, bacteria and parasites have opened up ways of designing novel vaccines which should both improve the quality and extend the range and value of vaccines as major prophylactic and therapeutic tools of the future. Two main strategies have emerged, one involving the development of synthetic vaccines which are essentially composed of selected epitopes of the pathogenic agent that will elicit neutralising antibodies. The other strategy attempts to make use of chimeric agents that will allow live virus or bacteria to be used as vectors for carrying appropriate epitopes of the target pathogen. Current knowledge about the immunology and improvements in the presentation of antigen to the immune system will also play an important role in the rational design of vaccines. This review summarises present methods of producing vaccines and considers the development of more rational methods of vaccine design that will greatly influence the production of vaccines in the future.
