The invention provides recombinant replicable vesiculoviruses. The
invention provides a method which, for the first time, successfully
allows the production and recovery of replicable vesiculoviruses, as well
as recombinant replicable vesiculoviruses, from cloned DNA, by a method
comprising expression of the full-length positive-strand vesiculovirus
antigenomic RNA in host cells. The recombinant vesiculoviruses do not
cause serious pathology in humans, can be obtained in high titers, and
have use as vaccines. The recombinant vesiculoviruses can also be
inactivated for use as killed vaccines.
