Recombinant MVA virus expressing dengue virus antigens, and the use thereof in vaccines
Recombinant MVA viruses containing and/or capable of expressing dengue virus antigens and the use of such recombinant MVA for vaccination.
1. A composition comprising a first and second component, wherein the first component is a vector comprising more than one DNA sequence selected from the group consisting of a DNA sequence encoding a Dengue virus serotype 1 antigen, a DNA sequence encoding a Dengue virus serotype 2 antigen, a DNA sequence encoding a Dengue virus serotype 3 antigen, or a DNA sequence encoding a Dengue Virus serotype 4 antigen and wherein the more than one DNA sequences are under the transcriptional control of a T7 RNA polymerase promoter and the second component is a recombinant Modified Vaccinia Ankara (MVA) virus comprising a DNA sequence encoding T7 RNA polymerase.
2. The composition of claim 1 , wherein the vector of the first component is a plasmid.
3. The composition according to claim 1 , wherein the DNA sequence encoding Dengue virus antigen is selected from the group consisting of DNA sequences encoding preM, E and NS1 antigens.
4. The composition according to claim 1 , wherein the DNA sequence encoding the t7 RNA polymerase is inserted at a site of a naturally occurring deletion with the MVA genome.
5. A cell containing the composition of claim 1 .
