The invention relates to HIV chimeric genes formed by the union of fragments of different genes of said virus, wherein said fragments contain epitopes for cytotoxic T cells (CTL) or HIV-1 auxiliary T cells, which are presented by a wide range of antigens of type 1 Major Human Histocompatibility System (HLA- 1). Recombinant poxvirus are obtained from said genes, which are useful for prophylactic and therapeutic vaccination against HIV/AIDS infection, are capable of generating a protective immune cell response in vaccinated laboratory animals and are recognized by the CTL lymphocytes of HIV/AIDS patients.
L'invention concerne des gènes chimères du VIH formés à l'aide de fragments de différents gènes de ce virus, ces fragments renfermant des épitopes pour des lymphocytes T cytotoxiques (CTL) ou T auxiliaires du VIH-1, représentés par une gamme étendue d'antigènes du système majeur d'histocompatibilité humain de type 1 (HLA-1). On obtient à partir de ces gènes des poxvirus recombinés utiles pour la vaccination préventive et thérapeutique contre l'infection par le VIH/SIDA, permettant de générer une réponse immune cellulaire protectrice chez des animaux de laboratoire immunisés et reconnus par les lymphocytes CTL de patients atteints par le VIH/SIDA.
