Abstract: The invention relates to a vaccine composition comprising a) at least one nucleic acid encoding at least one antigen or fragment or variant thereof; and b) a carrier composition, wherein the carrier composition comprises the phospholipid phosphatidylserine. The present invention further relates to a pharmaceutical composition comprising the vaccine composition and a pharmaceutically acceptable carrier, diluent or excipient, and to the vaccine composition or pharmaceutical composition for use in the treatment or prophylaxis of (as well as a corresponding method of treatment thereof) infectious diseases; cancer or tumor diseases, disorders or conditions; specific liver diseases; allergies; or autoimmune disease, disorder or condition; in a subject. Still further, the present invention is concerned with a kit or kit of parts, comprising the vaccine composition or the pharmaceutical composition as well as a method of inducing an immune response in a subject.

Abstract: The present invention provides a nucleic acid sequence comprising at least one miRNA binding site sequence containing at least one miRNA binding site. Those miRNA binding site sequences are located within and/or immediately 3 or 5? of the 5? UTR of a gene to reduce the off-target side effects and allow a cell type specific expression from the nucleic acid sequence within the target organ or organs. The invention further provides pharmaceutical compositions, as well as a method of promoting cell-type specific expression, comprising the nucleic acid sequence according to the invention for use in therapy.

Abstract: The present invention provides optimized nucleic acid molecules, methods for optimization of nucleic acid molecules and uses of optimized nucleic acid molecules. A modular design principle is provided that is suitable to generate a nucleic acid, particularly mRNA, which is tailored for a respective application. The nucleic acid molecules of the present invention can be obtained by the versatile combination of multiple modules on nucleic acid level. Such nucleic acid, e.g. mRNA, can be tailored by combining one or more modules, comprising (i) a nucleic acid moiety encoding a polypeptide of interest (e.g. a protein potentially producing a therapeutic outcome) and (ii) at least one further coding or non-coding nucleic acid moiety, e.g.

Abstract: The invention relates to mRNA comprising lipid nanoparticles and their medical uses. The lipid nanoparticles of the present invention comprise a cationic lipid according to formula (I), (II) or (III) and/or a PEG lipid according to formula (IV), as well as an mRNA compound comprising an mRNA sequence encoding an antigenic peptide or protein. The invention further relates to the use of said lipid nanoparticles as vaccines or medicaments, in particular with respect to influenza or rabies vaccination.
