Compositions and methods are presented that allow for detection and prediction of an immune response in a subject that is selected to receive or that has received a vaccine. In selected embodiments, whole blood is used as starting material to obtain both dendritic cells and T cells, and synthetic or recombinant polypeptide(s) are used that include an antigen of the vaccine. The dendritic cells are then exposed to the synthetic or recombinant polypeptide(s), and thusly exposed dendritic cells are combined with the T cells to generate antigen reactive T cells. For detection or quantification, the antigen reactive T cells are expanded in vitro prior to ELISPOT or FACS analysis. Advantageously, such systems and methods are especially suitable for ascertaining an immune response against cancer antigens following vaccination with an anti-cancer vaccine.

A method for producing reassortant influenza viruses is provided. Also provided are reassortant influenza viruses produced according to the method, as well as vaccines based on said reassortant influenza viruses.

Described herein are implantable devices comprising cells engineered to express and secrete antigens of infectious agents. The devices are useful for inducing protective immune responses against infectious agents.

The present disclosure relates to recombinant human adenoviruses engineered to express a structural protein of a coronavirus. The recombinant adenoviruses are suitable for active immunization against a coronavirus in a human subject. Additionally, immune globulin obtained from immunized human subjects is suitable for passive immunization of a coronavirus-infected human subject.

Provided herein are compositions comprising VHH conjugates and their uses in treating diseases.

The present invention discloses immunogenic compositions including recombinant peptides and proteins comprising human immunodeficiency viruses (HIV) antigens and immunogens, e.g., gp 120 protein peptides. In some aspects, the immunogenic composition comprises a secreted fusion protein comprising a soluble HIV viral antigen joined by in-frame fusion to a C-terminal portion of a collagen which is capable of self-trimerization to form a disulfide bond-linked trimeric fusion protein. In some aspects, the immunogenic compositions provided herein are useful for generating an immune response, e.g., for treating or preventing an HIV infection. In some aspects, the immunogenic compositions provided herein may be used in a vaccine composition, e.g., as part of a prophylactic and/or therapeutic vaccine. Also provided herein are methods for producing the recombinant peptides and proteins, prophylactic, therapeutic, and/or diagnostic methods, and related kits.

Self-assembling, cytocompatible peptides having the ability to form uniform nanorod assemblies are described. These peptides comprise a self-assembling β-sheet peptide and an amino terminal positively charged amino acid or amino acid analog, such as a lysine residue. Constructs comprising an antigen covalently attached to the self-assembling peptide are also disclosed, as well as the use of such constructs as vaccines for inducing an immune response against the antigen.

Disclosed are immunogenic constructs including: a nanoparticle; a cationic polymer electrostatically bound to an exterior surface of the nanoparticle and a stabilizer bound to the cationic polymer or the exterior surface of the nanoparticle; and an antigen or antigen producing agent. Optionally, the constructs may include adjuvant and/or one or more functional oligonucleotide(s) (e.g., siRNA or pDNA). Also disclosed are methods of using the provided immunogenic constructs for co-delivering an adjuvant, antigen, and optionally siRNA to a cell, inducing immune response in a subject, and treating or preventing an infectious disease in a subject.
