Abstract: The invention provides a method of inducing an immune response against a human immunodeficiency virus (HIV) in a mammal. The method comprises administering to the mammal an adenoviral vector composition comprising one or more adenoviral vectors encoding two or more different HIV antigens, the production of which induces an immune response against HIV in the mammal. The invention also provides an adenoviral vector composition comprising four adenoviral vectors encoding an HIV clade A Env protein, an HIV clade B Env protein, an V clade C Env protein, and a fusion protein comprising an HIV clade B Gag protein and Pol protein, respectively.

Abstract: These vaccines target H5N1, H1, H3 and other subtypes of influenza and are designed to elicit neutralizing antibodies, as well as cellular immunity. The DNA vaccines express hemagglutinin (HA) or nucleoprotein (NP) proteins from influenza which are codon optimized and/or contain modifications to protease cleavage sites of HA which affect the normal function of the protein. Adenoviral constructs expressing the same inserts have been engineered for prime boost strategies. Protein-based vaccines based on protein production from insect or mammalian cells using foldon trimerization stabilization domains with or without cleavage sites to assist in purification of such proteins have been developed. Another embodiment of this invention is the work with HA pseudotyped lentiviral vectors which would be used to screen for neutralizing antibodies in patients and to screen for diagnostic and therapeutic antivirals such as monoclonal antibodies.

Abstract: In one embodiment, the invention provides a multiclade HIV plasmid DNA or viral vector vaccine including components from different clades of Env (optionally Env chimeras) and Gag-Pol-(optionally)Nef from a single clade. The vaccine of the invention may further include V1, V2, V3, or V4 deletions or combinations thereof. In another embodiment, the invention provides multiclade HIV envelope immunogens.
