Abstract: Recombinant fusion proteins including a dengue virus EIII and an E2 subunit derived from a thermophilic bacterium are described. Also described are expression vectors including a polynucleotide that encodes the recombinant fusion protein and a promoter. Also described are vaccine compositions that include either the recombinant fusion protein, polynucleotide, or both. Also described are methods of generating an immune response to dengue virus serotype 2 comprising administering one or more of the disclosed vaccine compositions.

Abstract: The invention provides vaccination protocols for administering immunogens to a primate host in order to promote the formation of neutralizing antibodies (NAbs) against primate immunodeficiency viruses. In some embodiments, the vaccination protocols comprise the step of administering to a primate host a first immunogen comprising at least one primate immunodeficiency virus Envelope (env) sequence having a first set of consensus glycosylation sequences, followed by a second immunogen comprising at least one primate immunodeficiency virus env sequence having a second set of consensus glycosylation sequences, wherein the differences between the first set of consensus glycosylation sequences and the second set of consensus glycosylation sequences comprise differences in consensus glycosylation sequences observed in HIV isolates obtained at different time points of a natural infection.

Abstract: Vaccination by immunizing a mammalian host with a first HIV envelope immunogen having a minimum number of N- and O-linked glycosylation sites, followed by one or more booster immunizations with at least one second HIV envelope immunogen having more glycosylation sites than the first immunogen.
