The invention relates to an immunogenic or vaccine composition against the 2019 novel coronavirus (SARS-COV-2), comprising a nucleic acid construct encoding a SARS-COV-2 coronavirus Spike(S) protein antigen or a fragment thereof comprising the receptor-binding domain, wherein the nucleic acid construct sequence is codon-optimized for expression in 5 human.

Nucleic acid vaccine against the SARS-CoV-2 coronavirus

The invention relates to an immunogenic or vaccine composition against the 2019 novel coronavirus (SARS-COV-2), comprising a nucleic acid construct encoding a SARS-COV-2 coronavirus Spike (S) protein antigen or a fragment thereof comprising the receptor-binding domain, wherein the nucleic acid construct sequence is codon-optimized for expression in 5 human.

The invention relates to an immunogenic or vaccine composition against the 2019 novel coronavirus (SARS-CoV-2), comprising a nucleic acid construct encoding a SARS-CoV-2 coronavirus Spike (S) protein antigen or a fragment thereof comprising the receptor-binding domain, wherein the nucleic acid construct sequence is codon-optimized for expression in human.

The present invention is directed to a Zika virus (ZIKV) chimeric polyepitope comprising non-structural proteins and its use in an immunogenic composition. The present invention provides means, in particular polynucleotides, vectors and cells expressing said chimeric polyepitope. The present invention also relates to a composition or a vaccine comprising at least one of said polyepitope, polynucleotide, vector or host cell for use in the prevention of a ZIKV infection in a human subject, or for use in the prevention of ZIKV and dengue virus (DENV) infections in a human subject.

Zika virus chimeric polyepitope comprising non-structural proteins and its use in an immunogenic composition

The present invention relates to recombinant measles virus expressing Zika virus proteins and their applications, in particular in inducing preventive protection against Zika virus. The present invention is directed to recombinant measles virus (MV) expressing at least (i) the precursor of membrane (prM) protein of a Zika virus (ZIKV), and the envelope (E) protein of a ZIKV or a truncated version thereof, or (ii) the E protein of a ZIKV or a truncated version thereof, and concerns recombinant infectious particles of said MV-ZIKV able to replicate in a host after an administration, and also Virus Like Particles (VLPs) that contain these ZIKV proteins at their surface. The present invention provides means, in particular nucleic acids, vectors, cells and rescue systems to produce these recombinant infectious particles and VLPs. The present invention also relates to the use of these recombinant infectious particles and/or VLPs, in particular under the form of a composition, more particularly in a vaccine formulation, for the prevention of an infection by ZIKV or for the preventive protection against clinical outcomes of ZIKV infection.

Recombinant measles virus expressing zika virus prM and E proteins

The present invention is directed to a Zika virus (ZIKV) chimeric polyepitope comprising non-structural proteins and its use in an immunogenic composition. The present invention provides means, in particular polynucleotides, vectors and cells expressing said chimeric polyepitope. The present invention also relates to a composition or a vaccine comprising at least one of said polyepitope, polynucleotide, vector or host cell for use in the prevention of a ZIKV infection in a human subject, or for use in the prevention of ZIKV and dengue vims (DENV) infections in a human subject.

The present invention is directed to a dengue virus chimeric polyepitope composed of fragments of non-structural proteins and its use in an immunogenic composition against dengue virus infection. The present invention provides means, in particular polynucleotides, vectors, cells and methods to produce vectors expressing said chimeric polyepitopes, in particular vectors consisting of recombinant measles virus (MV) particles. The present invention also relates to the use of the recombinant MV particles, in particular under the form of a composition or of a vaccine, for the prevention and/or treatment of a dengue virus infection.

Dengue virus chimeric polyepitope composed of fragments of non-structural proteins and its use in an immunogenic composition against dengue virus infection

A method of directing evolution of a target polynucleotide of interest for obtaining variants of this target polynucleotide, a method to generate genetic variability by preparing a cell library, and a method to isolate or to screen variants of a polynucleotide or variants of a protein able to impact the phenotype of a cell or to confer a desired phenotype to target cells, and to identify theses polynucleotide variants or protein variants responsible for this phenotype are described.
