Abstract

The invention describes an adenovirus vector which carries a HIV structure gene of codon optimization and/or a HIV regulatory and auxiliary gene as well as a heterogenous promoter and a transcription terminator. When a first-booster immunization proposal is adopted by a single or combined plasmid vector vaccine, the vector-viral vaccine can be used for preventing HIV infection.

Description

1. Technical field [0001] The present invention relates to a codon-optimized polynucleotide or a fragment or derivative thereof. The present invention also relates to the polypeptide or protein encoded by the optimized nucleic acid sequence or its fragment or derivative. The present invention further relates to adenoviral vectors carrying the optimized polynucleotide and other viral vectors. The polynucleotide, polypeptide or protein and the viral vector carrying the polynucleotide can be used as a vaccine, preferably for the prevention of HIV infection. 2. Background technology [0002] Human immunodeficiency virus (Human Immunodeficiency Virus, HIV-1) is the pathogen of acquired immunodeficiency syndrome (Acquired human Immune Deficiency Syndrome, AIDS). [0003] AIDS (AIDS) has only been discovered for more than 20 years, and the number of people infected with AIDS in the world has reached 69 million, of which 32 million have died. At present, the AIDS epidemic in my c...
