11541114 · 2023-01-03 · ·

A vaccine comprising an immunologically effective amount of recombinant modified vaccinia Ankara (rMVA) virus which is genetically stable after serial passage and produced by a) constructing a transfer plasmid vector comprising a modified H5 (mH5) promoter operably linked to a DNA sequence encoding a heterologous foreign protein antigen, wherein the expression of said DNA sequence is under the control of the mH5 promoter; b) generating rMVA virus by transfecting one or more plasmid vectors obtained from step a) into wild type MVA virus; c) identifying rMVA virus expressing one or more heterologous foreign protein antigens using one or more selection methods for serial passage; d) conducting serial passage; e) expanding an rMVA virus strain identified by step d); and f) purifying the rMVA viruses from step e) to form the vaccine. One embodiment is directed to a fusion cytomegalovirus (CMV) protein antigen comprising a nucleotide sequence encoding two or more antigenic portions of Immediate-Early Gene-1 or Immediate-Early Gene-2 (IEfusion), wherein the antigenic portions elicit an immune response when expressed by a vaccine.

Human cytomegalovirus RNA vaccines

The disclosure describes HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Identification and Elimination of HCMV-Infected Cells

The invention relates to the use of a single heavy chain variable domain antibody against human cytomegalovirus protein US28, which antibody binds to the extracellular region including, for example, the N-terminal extracellular region and/or the extracellular loops of US28, for isolation of cells that are infected with cytomegalovirus and/or for ex vivo reactivation of cytomegalovirus in latently infected cells. The invention further relates to the anti-US28 antibody for use in a method of reactivating cytomegalovirus in infected cells, or in a method of eliminating infected cells. The invention further relates to a tissue, organ, or cells such as bone marrow stem cells, from which cells that were infected with CMV have been removed with the use of the anti-US28 antibody.
