The present invention provides for novel immunological and vaccine formulations comprising a newly applied non-crosslinked polyacrylic acid polymer adjuvant. The adjuvants may be combined with a wide variety of immunogens to produce vaccines that are safe and effective when administered to a wide range of target animals. The immunogens may include, but are not limited to: inactivated pathogens, attenuated pathogens, subunits, recombinant expression vectors, plasmids or combinations thereof. The animals may include, but are not limited to: humans, murine, canines, felines, equines, porcines, ovines, caprines and bovines.

Provided herein are recombinant polypeptides comprising a SARS-CoV-2 S1 protein binding domain polypeptide and a GM-CSF polypeptide, polynucleotide sequences encoding the same, virus-like particles comprising the same, and methods for using these compositions for the treatment of a SARS-CoV-2 infection in a subject, and for detection of a SARS-CoV-2 antibodies in a subject.

Adjuvants acting at the level of antigen presentation useful for stimulation of specific immunity against tumor endothelial cells. In one embodiment the invention teaches the use of activation of specific antigen presenting cell programs to selectively induce cytotoxic T cells and antibodies with complement activating ability while not evoking antigenic responses that potentially stimulate angiogenesis or growth of tumor endothelial cells. Specifically, the invention teaches selection and use of adjuvants that inhibit suppressive dendritic cell produced factors, surface bound and soluble, while stimulating activatory cytokines. Adjuvant means include innate activatory molecules, gene silencing means, alarmins, and other stimulatory means resembling “danger” signals.

The present invention relates to compositions, methods, and kits for eliciting an immune response to at least one CMV antigen expressed by a cancer cell, in particular for treating and preventing cancer. CMV determination methods, compositions, and kits also are provided.

Provided herein are cancer stem cell targeted cancer vaccines and methods for treating and vaccinating against cancer. Also contained herein are regimens by which cancer stem cell targeted cancer vaccines are administered, such regimens comprising peptides, compositions, immunomodulatory agents, and emulsifiers. Also provided are the patient populations to which the regimens are to be administered, and the dosages, schedules, route of administration for the regimens.

The present invention relates to new immunocytokines which are useful for the treatment of cancer. These fusion proteins comprise (i) an antibody or antigen-binding fragment thereof fused to (ii) a cleavable peptide linker, and (iii) cytokine, or functional fragments thereof. Methods of treatment using these immunocytokines are also disclosed.

This invention provides peptides, immunogenic compositions and vaccines, and methods of treating, reducing the incidence of, and inducing immune responses to a WT-1-expressing cancer, comprising peptides derived from the WT-1 protein.

Pan-coronavirus vaccines for inducing efficient, powerful and long-lasting protection against all Coronaviruses infections and diseases, comprising multiple highly conserved large sequences which may comprise one or more conserved B, CD4 and CD8 T cell epitopes that help provide multiple targets for the body to develop an immune response for preventing a Coronavirus infection and/or disease. In certain embodiments, the large sequences are conserved proteins or large sequences, e.g., sequences that are highly conserved among human coronaviruses and/or animal coronaviruses (e.g., coronaviruses isolated from animals susceptible to coronavirus infections).

The present invention comprises compositions, methods, and devices for creating an stimulating an antigen-specific dendritic cell immune response. Devices and methods provide prophylactic and therapeutic immunity to subjects against cancer and infectious agents.

The invention features methods to induce and maintain a protective cytotoxic T-lymphocyte response to a peptide of the HER2/neu oncogene, E75, with the effect of inducing and maintaining protective or therapeutic immunity against breast cancer in a patient in clinical remission. The methods comprise administering to the patient an effective amount of a vaccine composition comprising a pharmaceutically acceptable carrier, an adjuvant such as recombinant human GM-CSF, and the E75 peptide at an optimized dose and schedule. The methods further comprise administering an annual or semi-annual booster vaccine dose due to declining E75-specific T cell immunity. The invention also features vaccine compositions for use in the methods.
