Provided herein are recombinant modified vaccinia Ankara (rMVA) viral vectors comprising heterologous nucleic acid inserts encoding one or more SARS-CoV2 proteins, peptides, or fragments thereof, operably linked to a promoter compatible with poxvirus expression systems that, upon expression, are capable of inducing protective immunity. The compositions can be used in a priming vaccination strategy or in a prime/boost vaccination strategy to provide immunity to SARS-CoV2 and variants thereof.

Methods of inducing an immune response against human immunodeficiency virus (HIV) are described. In particular, methods of inducing an immune response against HIV by co-locally administering an immunogenically effective amount of an isolated HIV envelope (Env) polypeptide and an immunogenically effective amount of an adenovirus vector encoding an HIV antigen, e.g., Env antigen are described. The isolated HIV Env polypeptide and adenovirus vector can be administered in a single composition or in separate compositions, in which the composition or compositions do not contain an adjuvant.

A method for treating a patient comprising: (a) providing a composition comprising a population of T cells expressing both a chimeric antigen receptor (CAR) and a T cell receptor specific for a cytomegalovirus (CMV) antigen; (b) administering the composition to the patient; and (c) administering to the patient a viral vector encoding: (i) CMV pp65 and (ii) a fusion protein comprising exon 4 of CMV protein IE1 (e4) and exon 5 of CMV protein 1E2 (e5) either prior to or subsequent to administering the composition comprising a population of T cells to the patient is described.

This disclosure relates to methods of promoting immune responses against HIV and compositions related thereto. In certain embodiments, this disclosure relates to methods of vaccinating for HIV comprising administering to the subject a priming composition followed by a boosting composition. In certain embodiments, the priming composition comprises a recombinant virus such as recombinant MVA that encodes an Env protein of HIV or segment thereof. In certain embodiments, the boosting composition comprises a trimeric cyclically permuted gp120 chimeric protein reported herein or DNA encoding the same.

The present disclosure relates generally to the fields of oncology, virology and immunotherapy. It concerns poxviruses, specifically the highly attenuated modified vaccinia virus Ankara (MVA), and a recombinant modified vaccinia Ankara virus with deletion of vaccinia virulence factor E3 (MVAΔE3L), each further modified to express human Fms-like tyrosine kinase 3 ligand (Flt3L) or GM-CSF. The disclosure relates to use of the foregoing recombinant viruses as cancer immunotherapeutic agents. The foregoing recombinant poxviruses can also be used in combination with immune checkpoint blockade therapy.

The invention relates to a recombinant Modified Vaccinia Virus Ankara (MVA) expressing a TAA and the costimulatory molecule 4-1BBL for use in (i) the prevention of recurrence of a solid tumor, wherein the recombinant MVA is intratumorally administered to the solid tumor, or (ii) the treatment, prevention and/or prevention of recurrence of a tumor, wherein the recombinant MVA is intratumorally administered to another solid tumor.

The present invention relates to a pharmaceutical composition for treating cancer comprising an anticancer virus, an immune checkpoint inhibitor and hydroxyurea as active ingredients. The pharmaceutical composition for treating cancer of the present invention, comprising an anticancer virus, an immune checkpoint inhibitor and hydroxyurea as active ingredients, has an excellent anticancer effect and safety as compared to a conventional case of single administration of an anticancer virus or combined administration of an anticancer virus and an immune checkpoint inhibitor. Accordingly, the pharmaceutical composition for treating cancer of the present invention, comprising an anticancer virus, an immune checkpoint inhibitor and hydroxyurea as active ingredients, may be effectively used in treating cancer.

The present disclosure provides oncolytic viruses expressing a modulator of interferon regulatory factors (IRFs), and compositions comprising thereof. The present disclosure further provides methods of using said oncolytic viruses and compositions for treating cancer, and for improving a subject's responsiveness to an immunomodulatory agent (e.g., an immune checkpoint inhibitor).

The compositions and methods are described for generating an immune response to an antigen. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens as a fusion product with a viral glycoprotein and matrix protein for generating a protective immune response to a 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 diseases.

The present invention relates to recombinant modified vaccinia virus Ankara (MVA) and to methods of using the same. In particular, the invention relates to recombinant MVA comprising a nucleotide sequence encoding for a structural protein of an equine encephalitis virus (EEV) excluding encoding for a capsid protein of the EEV, a composition in particular a pharmaceutical composition, a vaccine or kit comprising the recombinant MVA, uses and methods thereof e.g., suitable for treating and/or preventing a western, Venezuelan, and/or eastern equine encephalitis virus caused disease.
