Impediments, imponderables and alternatives in the attempt to develop an effective vaccine against AIDS.

A personal view is presented that current successful vaccines against 'ordinary' viruses do not provide the guidelines needed for development of effective vaccines against the 'extraordinary' viruses that cause AIDS. Present 'candidate' AIDS vaccines fail to recognize the special attributes that are needed to make them successful. There is an urgent need for intensive studies of pathogenesis to seek and find the clues needed for vaccine attack that are at present unknown. Also needed is a targeted Research and Development organization comprising a cadre of capable scientists of requisite disciplines in adequate facilities, dedicated solely to the development of a vaccine against AIDS. The urgency imposed by the AIDS pandemic merits a new dedication to targeted basic research discovery and an effectively concentrated and coordinated applied research initiative.
