Disclosed herein are compositions that include antigen-encoding nucleic acid sequences having multiple iterations of KRAS neoepitope-encoding sequences and/or lacking immunodominant epitopes. Also disclosed are nucleotides, cells, and methods associated with the compositions including their use as vaccines.

A vaccine composition comprising at least one antigen and one adjuvant, characterized in that the adjuvant comprises sterile-filterable nanoparticles comprising pseudo-boehmite and polyacrylate.

Embodiments are directed to fibrillar adjuvants. Epitopes assembled into nanofibers by a short synthetic fibrillization domain elicited high antibody titers in the absence of any adjuvant.

Provided herein are methods and compositions for stabilization of active agents. The active agents are distributed, mixed or embedded in a silk fibroin matrix, thereby retaining the bioactivity of the active agents upon storage and/or transportation. In some embodiments, the storage-stable vaccine-silk compositions are also provided herein.

The technology provides immunogenic compositions comprising HIV-1 envelopes in supramolecular nanofiber complexes, which may also comprise a T-cell helper epitopes, and methods of using these compositions for induction of immune responses.

The technology provided herein relates to novel malaria vaccines composed of different recombinant proteins, in particular recombinant fusion proteins comprising several different Plasmodium falciparum antigens from the pre-erythrocytic, the blood, and the sexual parasite main stages. The proteins may be used in a mixture vaccine formulation to elicit protective immune responses in humans. Nucleic acid molecules encoding said recombinant proteins, vectors and host cells containing the nucleic acids and methods for preparation and producing such proteins are also disclosed, as well as antibodies induced or generated by the use of said malaria vaccines and the use of such antibodies or recombinant derivatives for passive immunotherapy.

In some aspects, provided herein are methods and compositions for treating or preventing adverse cardiac events in a patient who has suffered an invasive pneumococcal infection or is at risk of such an infection. The compositions include fusion proteins comprising a CbpA polypeptide or active fragment or variant thereof and optionally a T cell epitope (TCE) and a third immunogenic polypeptide from a bacteria.

The present disclosure provides nanostructures (e.g., monolayer or bilayer nanostructures) comprising porphyrins with cobalt chelated thereto such that the cobalt metal resides within monolayer or bilayer in the porphyrin macrocycle. The nanostructures can have presentation molecules comprising epitopes from microorganisms with a histidine tag attached thereto, such that at least a part of the his-tag is within the monolayer or bilayer and coordinated to the cobalt metal core and the presentation molecules are exposed to the outside of the nanostructures. The nanostructures can further comprise a cargo. The nanostructures can be used to deliver the cargo to an individual.

The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein. It also discloses its use for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the treatment of cancer or tumour diseases. The present invention further describes a method for increasing the expression of a peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.

Provided herein are vaccine composition comprising a chemically-modified messenger ribonucleic acid (mRNA) encoding a hMPV fusion (F) glycoprotein and a chemically-modified mRNA encoding a hPIV3 F glycoprotein formulated in a cationic lipid nanoparticle formulation, and related method for inducing an antigen-specific immune response.
