Immunization methods are provided. The methods typically include administering the subject an effective amount of an antigen and adjuvant to induce an immune response against an antigen, the method including two or more of (i) slow prime delivery of antigen and/or adjuvant, a (ii) temporally delayed 2nd immunization, and (iii) a robust adjuvant. Element (i) can be or include temporally extended exposure of antigen, adjuvant, or preferably the combination thereof, such as one or more of repeated administrations, infusion optionally by osmotic pump and escalating dosing. Element (ii) can include administering one or more boost doses of antigen and/or adjuvant, for example between 11 and 35 weeks after the start of the prime administration. A preferred robust adjuvant (iii) is one including non-liposome, non-micelle particles formed of a lipid, an additional adjuvant such as a TLR4 agonist, a sterol, and a saponin.

The present invention relates to a cyclic peptide, a conjugate comprising said cyclic peptide and a lipopeptide building block, a bundle of said conjugates, a synthetic virus-like particle comprising at least one bundle of conjugates and pharmaceutical compositions comprising the same. The present invention further relates to said cyclic peptide, said conjugate said bundle of conjugates, said synthetic virus-like particle and said pharmaceutical compositions for use as a medicament, preferably for use in a method for preventing of an infectious disease or reducing the risk of an infectious disease, more preferably for use in a method for preventing or reducing the risk of an infectious disease associated with or caused by a respiratory syncytial virus.

Gas-filled microvesicles comprising an antigen bound thereto and to aqueous suspensions containing said microvesicles, for use in immunomodulating formulations, in particular as a vaccine. The antigen is covalently bound to a component of the microvesicles envelope. The microvesicles of the invention, comprising a molar excess of fatty acids in the stabilizing envelope, are particularly effective in the uptake by antigen-presenting cells, in particular dendritic cells.

Described herein are compounds for use in vaccine compositions which contain natural or synthetic carbohydrate antigens. Such vaccines may be highly immunologically active due to the conjugation with an immune-stimulating protein or with a monophosphorylated lipid A derivative, and may be self-adjuvanting due to the presence of a monophosphorylated lipid A derivative. Treatments for cancer and fungal and bacterial infections are described herein.

Provided herein are therapeutic nucleic acid molecules for managing, preventing and/or treating infectious diseases caused by coronavirus. Also provided herein are therapeutic compositions, including vaccines and lipid nanoparticles, comprising the therapeutic nucleic acids and related therapeutic methods and uses.

The present invention relates to compositions and methods for inducing an immune response against influenza virus in a subject. In some embodiments, the present invention provides a composition comprising a nucleoside-modified nucleic acid molecule encoding at least one influenza virus antigen, such as a hemagglutinin antigen or a fragment thereof, neuraminidase antigen or a fragment thereof, nucleoprotein antigen or a fragment thereof, matrix protein 1 antigen or a fragment thereof, or matrix-2 ion channel antigen or a fragment thereof.

A method of treating a metastatic lesion that presents a peptide containing SLLQHLIGL (SEQ ID NO: 310) on a cell surface, including selecting a patient having a metastatic lesion and administering to the patient a composition containing recombinant T lymphocytes or activated T lymphocytes that express a T cell receptor, or a functional fragment thereof, that is reactive with, or binds to, an MHC ligand containing SLLQHLIGL (SEQ ID NO: 310).

Antibodies and method of making antibodies, either monoclonal or polyclonal wherein said antibodies have dual or multi-specific binding capacity to more than one type of antigenic epitope. The antibodies have simultaneous or independent recognition subsites to each of the epitopes. Antigenic epitopes include lipids, peptides, proteins, amino acid sequences, sugars and carbohydrates. Monoclonal antibodies and a method of making monoclonal antibodies of the invention include monoclonal antibodies that are broadly neutralizing to HIV-1 or other envelop viruses wherein the monoclonal antibody has subsites that simultaneously recognize protein and lipid epitopes from the virus.

The disclosure relates to respiratory virus ribonucleic acid (RNA) vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

The present invention relates to a composition comprising the OspA fusion protein of SEQ ID NO: 1 (LipSID1-S2D1), the OspA fusion protein of SEQ ID NO: 2 (Lip-S4D1-SShybD1) and the OspA fusion protein of SEQ ID NO: 3 (Lip-S5D1-S6D1) for use in a vaccine or for use in a method for eliciting an immune response in a human against Lyme disease.
