An antigenic and immunogenic composition of predetermined inactivated strains of human immunodeficiency virus (HIV) is disclosed. Inactivation is through psoralen and ultraviolet radiation; the composition is rendered more effective by the removal of structural features of HIV that interfere with immune response. In particular, sialic acid is removed to enhance immune recognition of the composition and to impair Complement Factor H binding. CD55 and CD59 are also removed to prevent the binding of Complement Factor H. Determination of strains for inactivation may be though immunotherapeutic genotyping or probabilistic assessment of risk of exposure. |
