"Vu00ecrus respiratory syncytial (RSV) human group B, isolated, recombinantemente generated, attenuated vaccine, a process to immunize a indivu00ecduo to induce protection against RSV subgroup B,The composition, process for producing infectious RSV subgroup B attenuated, and isolated nucleic acid molecule are described sinciciais respiratory virus attenuated recombinantemente generated.Isolates of subgroup B, having at least a mutation in the gene atenuadora RNA polymerase. They are formulated vaccines comprising such virus and a physiologically acceptable vehicle.The vaccines are used to immunize an individual to induce protection against respiratory viruses sinciciais.
