STD vaccines--an overview.

OBJECTIVES

To describe the role and current status of vaccine research against sexually transmitted diseases (STDs).

METHODS

The available literature was reviewed with particular emphasis on bacterial STDs.

RESULTS

Strategic approaches to possible implementation of STD vaccine programmes were analysed. The status of vaccines against bacterial STDs (syphilis, chancroid, gonorrhoea, and chlamydia) is described in detail.

CONCLUSIONS

The development of safe and effective STD vaccines offers a potent tool for the control of STDs, including direct and indirect prevention of HIV infection. Future priorities should be in the development of vaccines against gonorrhoea, chlamydia, and syphilis. When such vaccines become available, caution should be exercised to ensure that they do not interfere with the effectiveness of other prevention programmes.
