The frightening pace of the worldwide spread of the human immunodeficiencyvirus (HIV) demands that priority be placed on the developmentof an effective vaccine1. Two distinct populations of virusesresponsible for the acquired immunodeficiency syndrome (AIDS)have been defined: HIV type 2 (HIV-2), the viral group responsiblefor AIDS in West Africa, and HIV type 1 (HIV-1), the viral groupthat accounts for the AIDS epidemic in Central Africa and therest of the world2. The genomes of both HIV groups encode forthree structural proteins: an envelope glycoprotein that constitutesthe viral outer coat, a core . . . [Full Text of this Article]
