The invention relates to the field of immunity against Coronaviruses. In this respect, the invention provides vectorized antigens derived from Coronaviruses that trigger an immune response against Coronaviruses. The invention accordingly relates to an active ingredient which is a live attenuated recombinant measles virus expressing Coronavirus antigen(s) and to its use in eliciting immunity, in particular protective immunity against SARS-CoV-2 strain and advantageously broad-spectrum protective immunity against various strains of Coronaviruses.

Provided herein, inter alia, are compositions and methods including recombinant oncolytic viruses expressing CD47 antibody for the treatment of diseases including cancer, immune disorders, and infectious disease.

The present invention relates to prime-boost regimens that involve the administration of at least one mRNA construct, such as the use of such constructs in “boost” administration subsequently to “prime” administration of certain other antigenic composition(s). Such inventive regimens may, in particular, be useful for the induction of an immune response in a subject, and/or the vaccination of such subject against infection from one or more pathogens, and/or the treatment or prevention of one or more diseases or conditions, including a tumour or cancer, allergy or autoimmune conditions, and/or a disease or condition associated with infection from a pathogen. The present invention further describes methods, uses, vaccination compositions, kits and packaged vaccine components related to or useful for one or more of such regimens.

This disclosure provides replication-incompetent adenoviral vectors useful in vaccine development and gene therapy. The disclosed vectors comprise a selective deletion of E3 and are particularly useful for preparation of vaccines development and for gene therapy using toxic transgene products that result in vector instability that occurs when the entire E3 domain is deleted.

The compositions and methods are described for generating an immune response to a hemorrhagic fever virus such as ebolavirus, Marburgvirus, or arenavirus. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to a member of genus Ebolavirus (such as a member of species Zaire ebolavirus), a member of genus Marburgvirus (such as a member of species Marburg marburgvirus), or a member of genus Arenavirus (such as a member of species Lassa virus) in the subject to which the vector is administered. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat an infection caused by ebolavirus, Marburgvirus, or arenavirus.

The present invention relates to isolated polynucleotide and polypeptide sequences derived from novel chimpanzee adenovirus ChAd157, as well as to recombinant polynucleotides, vectors, adenoviruses, cells and compositions comprising said polynucleotide and polypeptide sequences.

The present invention relates to the use of an immunogenic composition that comprises a porcine circovirus type 3 (PCV3) antigen for treatment of several clinical manifestations (diseases). Preferably, the clinical manifestations are associated with a PCV3 infection.

Disclosed herein are compositions that include antigen-encoding nucleic acid sequences and/or antigen peptides. Also disclosed are nucleotides, cells, and methods associated with the compositions including their use as vaccines, including vectors and methods for a heterologous prime/boost vaccincation strategy.

Provided are methods of making and delivering vaccine compositions using an enucleated cell-based platform. Methods of clearing pathogenic infections in a subject using the enucleated cell-based platform is also provided. Such enucleated cell-based platform reduces the vaccine development timeline as compared with conventional biological vaccines, and improves vaccine efficacy.

Provided herein are genetically modified arenaviral vectors suitable as vaccines for prevention and treatment of cytomegalovirus infections and reactivation. Also provided herein are pharmaceutical compositions and methods for the treatment of cytomegalovirus infections and reactivation. Specifically, provided herein are pharmaceutical compositions, vaccines, and methods of treating cytomegalovirus infections and reactivation.
