Computational prediction of immunogenic epitopes is a promising platform for designing therapeutic and preventive vaccines. A potential target is, for example, the human immunodeficiency virus (HIV-1) for which, despite decades of efforts, no vaccine is available. Indeed, due to the enormous variability of the virus, a single formulation effective against all or most HIV strains might not be achievable. Moreover, upon infecting host cells, HIV-1 can integrate in the host genome and form long lasting latent reservoirs that are not susceptible to common antiretroviral treatments. Therefore, a therapeutic vaccine designed to eliminate infected cells might represent a key component of strategies aimed at curing the infection. We herein introduce an automated algorithm to produce personalized and population-based vaccines.

An immune preparation includes an immune substance formed by polyinosinic-polycytidylic acid, a non-antibiotic amino compound, polyethyleneimine, and at least one metal ion. The immune preparation does not include any antibiotics to prevent potential side effects. The amino compound may be chitosan oligosaccharide. The immune preparation is suitable for mucosal administration. The mucosal immune preparation facilitates mucosal immunity of human body allowing for the activation and proliferation of various immune cells.

The present invention concerns a nucleotide sequence expressing a fusion protein, said fusion protein comprising or consisting of an exosome-anchoring protein fused at its C-terminus with an antigen, or a DNA expression vector comprising said nucleotide sequence, for use as vaccine.

The present invention provides methods, compositions, systems, and kits comprising nano-satellite complexes and/or serum albumin carrier complexes, which are used for modulating antigen-specific immune response (e.g., enhancing anti-tumor immunity). In certain embodiments, the nano-satellite complexes comprise: a) a core nanoparticle complex comprising a biocompatible coating surrounding a nanoparticle core; b) at least one satellite particle attached to, or absorbed to, the biocompatible coating; and c) an antigenic component conjugated to, or absorbed to, the at least one satellite particle component. In certain embodiments, the complexes further comprise: d) an type I interferon agonist agent. In some embodiments, the serum albumin complexes comprise: a) at least part of a serum albumin protein, b) an antigenic component conjugated to the carrier protein, and c) a type I interferon agonist agent.

The invention provides pharmaceutical compositions comprising inventive vaccine nanocarriers. The present invention provides methods of designing, manufacturing, and using inventive vaccine nanocarriers and pharmaceutical compositions thereof. The invention provides methods of prophylaxis and/or treatment of diseases, disorders, and conditions comprising administering at least one inventive vaccine nanocarrier to a subject in need thereof.

The invention provides a vaccine composition comprising a flavi peptide comprising one or more CD8+ T cell epitopes.

The present disclosure relates to immunostimulatory compositions that are effective in eliciting immune responses in avian species. More specifically, these immunostimulatory compositions comprise an immunomodulator composition and an immunostimulatory oligonucleotide that when administered stimulate toll-like receptor 21.

A method for synthesizing cell membrane-biomimetic nanotherapeutics can include coating core particles with cell membrane materials using flash nanocomplexation (FNC). FNC is a turbulent mixing and self-assembly method that can produce cell membrane-coated nanotherapeutics in a reproducible and scalable manner. The FNC-produced cell membrane-coated particles demonstrate lower aggregation, polydispersity, and zeta potential, than nanoparticles prepared by conventional coating methods, such as conventional bulk-sonication. As such, the present method achieves more complete, homogeneous and controllable coating than conventional bulk-sonication methods.
