Highly infectious rubella virus cDNA clones derived from infectious cDNA clone having a low specific infectivity and methods of obtaining highly infectious rubella virus cDNA clones. Togavirus expression vectors of improved stability for the expression of live, attenuated togavirus and a foreign gene, based on the nucleic acid sequence of an infectious rubella virus clone and contain a togavirus non-structural protein open reading frame; an expression element for expression of a foreign gene; a foreign gene or a multiple cloning site for insertion of a foreign gene; an expression element for the expression of the live, attenuated togavirus; and a togavirus structural protein open reading frame. The expression element is either a subgenomic promoter or an internal ribosome entry site (IRES). Administration of the vector as an immunization agents is useful for the induction of immuity against the togavirus, the foreign gene, or both.
A rubella virus expression vector, comprising a rubella virus non-structural protein open reading frame, a subgenomic promoter for expression of a foreign gene, operably linked to the foreign gene or a multiple cloning site for insertion of the foreign gene, and an internal ribosome entry site, operably linked to a rubella virus structural protein open reading frame.
A method of producing a rubella virus expression vector, comprising operably linking
