A mutant herpesvirus that can be used a recombinant virus vector includes (a) a mutation such that the mutant virus has a reduced ability in comparison with a parent type to cause lysis of an infected cell, and (b) an inactivating mutation in a gene essential for the production of infectious virus. An example is a HSV1 mutant lacking the essential glycoprotein gH gene and having a mutation impairing the function of the gene product VP16. A heterologous gene can be carried at the site of the inactivated essential gene, e.g. a gene suitable for administering gene therapy. The vector has an increased margin of safety over known herpesvirus vectors in respect of incidence of cytopathic effects and/or risk of infection.

Live-attenuated vaccines against Edwardsiella ictaluri or against Pasteurella piscicida are disclosed. Both vaccines are incapable of reversion to virulence, because both are made by deletion mutations in the aroA gene, the purA gene, or both. These vaccines may be used not only to vaccinate fish against Edwardsiella ictaluri or Pasteurela piscicida, but also to serve as vectors to present antigens from other pathogens to the fish, thereby serving as vaccines against other pathogens as well, with no risk of infection by reversion to the virulent form of the pathogen in which the antigen occurs naturally.
