Populærvitenskapelig sammendrag av avhandlingen:
Modified vaccinia virus Ankara (MVA) is a “weak” live virus used as a smallpox and monkeypox vaccine. It is also a promising vector vaccine against different diseases. One concern about the extensive use of MVA/MVA vectored vaccine is that it may exchange genes with a “stronger” relative like cowpox virus (CPXV). There is few information about the diversity, evolution and genetic exchanges among CPXV and its relatives. Therefore, we analysed the genome of CPXVs and found that CPXVs were genetically different to be grouped as one species. Additionally, we found one natural recombinant CPXV that had DNA from other three species. In the laboratory we co-infected and superinfected cells with CPXV and MVA vectored vaccine. Our analysis indicated that the viruses exchanged significant genetic material producing progeny viruses with mosaic genomes. Some hybrid viruses gained genes that were absent in MVA. This information is relevant to the production of MVA/MVA vectored vaccine with improved biosafety profile.
