Abstract:
The invention provides isolated nucleic acids encoding recombinant genomes or antigenomes of Human Parainfluenza Viruses that are useful as vaccines. The recombinant genomes or antigenomes can be incorporated into expression vectors for production of recombinant viruses in vitro. The invention also provides recombinant Human Parainfluenza viruses having one or more mutations that attenuate replication of the virus in a host.

Abstract:
Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an anti-PIV immune response or as vectors for introducing heterologous genes into a host. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different PIV virus to form the human-bovine chimeric PIV genome or antigenome.
