A method of vaccinating a subject is provided, where a cancer protective response is produced. A first vaccine comprises an adenovirus vector comprising at least one nucleic acid molecule that produces a cancer protective response is administered, followed by one or more second vaccines comprising an alphavirus replicon particle comprising RNA comprising or produced from the nucleic acid molecule. In an embodiment the cancer is prostate cancer.

The present invention relates to an immunogenic composition against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), especially to an immunogenic composition having a recombinant SARS-CoV-2 S protein and adjuvant.

A method of reducing or preventing the development of airway inflammation in a subject includes the step of infecting the respiratory tract of a subject an amount of a composition including a pharmaceutically acceptable carrier and live attenuated pertactin-deficient Bordetella bacteria sufficient to colonize the respiratory tract of the subject. The step of infecting the subject with the live attenuated pertactin-deficient Bordetella bacteria results in reduction or prevention of the development of airway inflammation in the subject.

A method of carrying out adoptive immunotherapy by administering a subject an antigen-specific cytotoxic T lymphocytes (CTL) preparation in a treatment-effective amount is described. In the method, the CTL preparation is preferably administered as a preparation of an in vitro antigen-stimulated and expanded primate CTL population, the CTL population: (i) depleted of FoxP3+ T lymphocytes prior to antigen stimulation, (ii) antigen-stimulated in vitro in the presence of interleukin-21; or (iii) both depleted of FoxP3+ T lymphocytes prior to antigen stimulation and then antigen-stimulated in vitro in the presence of interleukin-21. Methods of preparing such compositions, and compositions useful for carrying out the adoptive immunotherapy, are also described.

The invention is in the field of prevention or treatment of diseases, in particular infectious diseases, and more particularly in the field of multivalent vaccines. The inventors characterized 5′ copy-back DI-RNAs produced by recombinant MV strains, including rMV-based vaccines and wild-type MV (wt-MV). The efficiency of these DI-RNAs productions in different cell types was compared. For the first time 5′ copy-back DI-RNAs specific binding to RIG-I, MDA5 and LGP2 was assessed and linked to functional outcome in type-I IFN signalling. The inventors provide a composition of products comprising at least (i) a mixture of particles of a rescued recombinant MV-derived virus encoding at least one antigen (ii) a recombinant and/or purified protein, comprising at least one antigen. Regardless of the presentation of the products, and in particular regardless of whether the products are separated or readily separable or presented as a mixture.

The disclosure relates to compositions and methods for the preparation, manufacture and therapeutic use of combinations of immunomodulatory polynucleotides (e.g., mRNAs) encoding an immune response primer polypeptide (e.g., an interleukin 23 (IL-23) polypeptide or an interleukin 36γ (IL-36-gamma) polypeptide), and an immune response co-stimulatory signal polypeptide (e.g., an OX40L polypeptide).

A needleless injector which can selectively induce the immune response and a method for introducing DNA including a region coding for an antigen to selectively produce an antibody in a living body of a mammal by using the needleless injector are provided. Disclosed is a needleless injector for injecting a DNA solution into an injection target area without using any injection needles. The needleless injector includes an accommodating unit which accommodates the DNA solution, a predetermined ignition device; and a predetermined nozzle unit. A temperature of the predetermined combustion product, which is provided during the pressurization, changes to a neighborhood of ordinary temperature within 20 msec after a pressure, which is applied to the DNA solution on account of the combustion of the igniter powder, reaches an initial peak discharge force during a pressurization process for discharging the DNA solution.

Disclosed herein are compositions comprising structurally modified DNA encoded antibodies (DMAbs), methods of structurally modifying DMAbs, and methods of using structurally modified DMAbs.

The present disclosure describes compositions and methods for treating ornithine transcarbamylase (OTC) deficiency. The compositions include a lipid formulation and messenger RNA (mRNA) encoding an OTC enzyme. The lipid formulations can comprise an ionizable cationic lipid in a lipid nanoparticle encapsulating the mRNA.

The present invention relates to a composition for use in the treatment of an intestinal tract disorder caused by a gluten-associated protein, said composition comprising at least one agent which binds to the gluten-associated protein, characterized in that the composition is administered at the same time as or at most within 60 minutes after administration of at least one tannin to a patient.
