Abstract: The disclosure is directed to a coding RNA encoding an antigenic polypeptide which is selected or derived from Escherichia coli FimH. The present disclosure is also directed to compositions and vaccines comprising said coding RNA. Further, the disclosure concerns a kit, particularly a kit of parts comprising the coding RNA, or the composition, or the vaccine. The disclosure is also directed to methods of treating or preventing a disorder caused by E. coli.

Abstract: The invention is directed to a coding RNA for a Rotavirus vaccine. The coding RNA comprises at least one coding region encoding at least one antigenic peptide or protein of a Rotavirus, in particular VPS* of a Rotavirus, or immunogenic fragment or immunogenic variant thereof. The present invention is also directed to compositions and vaccines comprising said coding RNA in association with a polymeric carrier, a polycationic protein or peptide, or a lipid nanoparticle (LNP). Further, the invention concerns a kit, particularly a kit of parts comprising the coding RNA, or the composition, or the vaccine. The invention is also directed to a kit or kit of parts, medical treatments, and the first and second medical uses.

Abstract: The invention relates to vaccines providing protection against infections caused by members of the Pasteurellaceae family comprising outer membrane vesicles as the only active components, wherein the outer membrane vesicles are obtained from one or more strains of the Pasteurellaceae family, with the proviso that hypervesiculating strains are excluded. The invention also relates to a method for preparing such a vaccine.
