The invention describes chimeric Flavivirus constructs comprising lyssavirus G proteins in the E/NS1 intergenic region.

Chimeric flavivirus lyssavirus vaccines

The present invention relates to a series of novel compounds, methods to prevent or treat viral infections in animals by using the novel compounds and to said novel compounds for use as a medicine, more preferably for use as a medicine to treat or prevent viral infections, particularly infections with RNA viruses, more particularly infections with viruses belonging to the family of the Flaviviridae, and yet more particularly infections with the Dengue virus. The present invention furthermore relates to pharmaceutical compositions or combination preparations of the novel compounds, to the compositions or preparations for use as a medicine, more preferably for the prevention or treatment of viral infections. The invention also relates to processes for preparation of the compounds.

Viral replication inhibitors

The invention relates to polynucleotides comprising the sequence of a flavivirus preceded by a sequence encoding an N terminal part of a flavivirus Capsid protein, an immunogenic protein, or a part thereof comprising a an immunogenic peptide, and a 2A cleaving peptide, and to the virus encoded by such sequences. The invention further relates to the use of such polynucleotides and viruses as vaccines.

Live-attenuated flaviruses with heterologous antigens

The present invention relates to a series of novel compounds, methods to prevent or treat viral infections in animals by using the novel compounds and to said novel compounds for use as a medicine, more preferably for use as a medicine to treat or prevent viral infections, particularly infections with RNA viruses, more particularly infections with viruses belonging to the family of the Flaviviridae, and yet more particularly infections with the Dengue virus. The present invention furthermore relates to pharmaceutical compositions or combination preparations of the novel compounds, to the compositions or preparations for use as a medicine, more preferably for the prevention or treatment of viral infections. The invention also relates to processes for preparation of the compounds. 

The present invention relates to chimeric yellow fever&#x2014;Zika strains and attenuated versions thereof, wherein the nucleotide sequence encoding the signal sequence and prME protein of said yellow virus is replaced by a nucleotide sequence encoding the signal sequence and the prME protein of a Zika virus.

Chimeric yellow fever ZIKA virus strain

The invention relates to the use of a bacterial artificial chromosome (BAC) for the preparation of a vaccine, wherein the BAC comprises an inducible bacterial ori sequence for amplification of the BAC to more than 10 copies per bacterial cell. Plus a viral expression cassette comprising a cDNA of an attenuated RNA virus genome and comprising cis-regulatory elements for transcription of said viral cDNA in mammalian cells and for processing of the transcribed RNA into infectious viral RNA.
