The invention relates to a method of increasing the yield of virus, virus particles, or viral vectors from host cells in a bioreactor. The invention provides a reproducible and robust method and system of determining and controlling the optimal time of infection of host cells using a correlation of process air parameters including Air flow, O.sub.2 flow, and respective trends thereof resulting in increased virus yield.

The present invention relates to the field of oncolytic viruses and in particular to a recombinant rhabdovirus, such as vesicular stomatitis virus encoding in its genome for a CCL21 protein. The invention is further directed to the use of the recombinant virus in the treatment of cancer, and also to methods for producing such viruses.

Provided herein are methods for enhancing infection, growth, spread, or titer of an oncolytic RNA virus in a cancer or tumor cell; enhancing the oncolytic activity, cytokine-induced cell death activity, and/or cytotoxic activity of an oncolytic RNA virus in a cancer or tumor cell; upregulating cytokine response to, and/or enhancing the immunotherapeutic activity of an oncolytic RNA virus in a cancer or tumor cell; and/or treating a tumor or cancer in a subject in need thereof. Such methods employ a vanadium-containing compound, administered to the cancer or tumor cells before, after, or concurrently with infection of the cancer or tumor cells with the oncolytic RNA virus. Related compositions, uses, and kits therefor are also provided. Methods for producing RNA viruses, RNA virus-based cancer vaccines, and RNA virus-based cancer gene therapy vectors are also provided.

Disclosed herein is an oncolytic recombinant Maraba virus whose genome comprises one or more nucleic acid sequences that, in combination, encode an interleukin-12 (IL12) protein or a functional portion thereof. A method for treating a cancer in a patient using the oncolytic recombinant Maraba virus is also disclosed. The present disclosure also provides a tumour cell infected with an oncolytic rhabdovirus whose genome comprises one or more nucleic acid sequences that, in combination, encode an interleukin-12 (IL12) protein or a functional portion thereof, for use as an infected cell vaccine (ICV) for the treatment of a cancer. A method for treating a cancer in a patient using the infected cell vaccine is also disclosed.

The present invention includes a vaccine comprising a SARS-CoV-2 spike protein (S) or portion thereof, and methods of use thereof.

The present invention includes a vaccine comprising a SARS-CoV-2 spike protein (S) or portion thereof, and methods of use thereof.

This document provides methods and materials related to vesicular stomatitis viruses. For example, vesicular stomatitis viruses, nucleic acid molecules encoding VSV polypeptides, methods for making vesicular stomatitis viruses, and methods for using vesicular stomatitis viruses to treat cancer are provided.

The present invention relates to high-titer hybrid vims vectors which produce virus-like vesicle (VLVs) and compositions and methods thereof for targeting a malignancy or infectious disease. VLVs are a capsid-free, self-replicating artificial virus platform carrying positive-strand capped and polyadenylated RNA encoding an in vitro evolved Semliki Forest vims (SFV) RNA-dependent RNA replicase and the vesicular stomatitis virus (VSV) glycoprotein. The VLVs of the present invention and pharmaceutical compositions thereof encode for polynucleotide and/or polypeptide therapeutic agents useful in methods for the treatment, prophylaxis, and prevention of malignancies and infectious diseases.

The present invention includes a vaccine comprising a SARS-CoV-2 spike protein (S) or portion thereof, and methods of use thereof.

The present disclosure relates to a method for stimulating tumor antigen-specific immune responses comprising cancer vaccination involving the blockade or inhibition of interferon signaling. In particular, the method comprises administering an inhibitor of interferon signaling and a cancer vaccine comprising a tumor antigen, wherein the inhibitor of interferon signaling is administered before the cancer vaccine.
