A nucleic acid composition comprising (a) at least three different nucleic acid molecules encoding glycoproteins of the gp120 envelope of human immunodeficiency virus 1 (HIV-1), wherein each nucleic acid molecule encodes a glycoprotein of the envelope of a primary isolated strain of a clade selected from the group consisting of clades A, B, C and E; and (b) a nucleic acid molecule that encodes an HIV gag protein from a primary isolated strain. |
