    Abstract: The present invention relates to RNA therapy and, in particular, decreasing immunogenicity of RNA. Specifically, the present invention provides methods for decreasing immunogenicity of RNA, said methods comprising modifying the nucleotide sequence of the RNA by reducing the uridine (U) content, wherein said reduction of the U content comprises an elimination of U nucleosides from the nucleotide sequence of the RNA and/or a substitution of U nucleosides by nucleosides other than U in the nucleotide sequence of the RNA. Using RNA having decreased immunogenicity allows administration of RNA as a drug to a subject, e.g. in order to obtain expression of a pharmaceutically active peptide or protein, without eliciting an immune response which would interfere with therapeutic effectiveness of the RNA or induce adverse effects in the subject.

    Abstract: The present disclosure relates to a binding agent comprising a first and a second binding domain, wherein the first binding domain is capable of binding to a coronavirus spike protein (S protein) and the second binding domain is capable of binding to the coronavirus S protein, and wherein the first and second binding domains bind to different epitopes of the coronavirus S protein. Moreover, the disclosure relates to an antibody capable of binding to a coronavirus spike protein (S protein). The disclosure also relates to a nucleic acid such as RNA encoding the binding agent, in particular antibody, disclosed herein and a host cell transformed or transfected with said nucleic acid. Furthermore, the disclosure relates to a medical use of said binding agent, antibody, or nucleic acid. The agents and medical uses described herein are, in particular, useful for the prevention or treatment of coronavirus infection in a subject.
