Abstract
This invention provides cold adapted mutant RSV, specifically, mutant RSV of subgroup A and B. Nucleic acid molecules encoding the mutant RSV of this invention, and immunogenic polypeptides of these mutant RSV also are provided by this invention. Pharmaceutical compositions containing any of the above compositions are provided herein. These are especially useful as vaccines. Further provided by this invention are methods of vaccinating a subject against RSV infection using the pharmaceutical compositions described herein.
Claims15
A cold adapted mutant respiratory syncytial virus which is more attenuated in African green monkeys than the TS-1 respiratory syncytial virus mutant, wherein the mutant is derived from 3A strain of respiratory syncytial virus.
A pharmaceutical composition comprising a cold adapted mutaril respiratory syncytial virus which is more attenuated in African green monkeys than the TS-1 respiratory syncytial virus mutant, and a pharmaceutically acceptable carrier, wherein the mutant is derived from 3A strain of respiratory syncytial virus.
A method of vaccinating against respiratory syncytial viral infection in a subject mammal comprising administering to the subject mammal an effective immunizing amount of a pharmaceutical composition comprising a cold adapted mutant respiratory syncytial virus which is more attenuated in African monkeys than the TS-1 respiratory syncytial virus mutant, and a pharmaceutically acceptable carrier, wherein the mutant is derived from 3A strain of respiratory syncytial virus.
A cold adapted mutant respiratory syncytial virus which is more attenuated in African green monkeys than the TS-1 respiratory syncytial virus mutant, wherein the mutant is dcrivcd from 2B strain of respiratory syncytial virus.
A pharmaceutical composition comprising a cold adapted mutant respiratory syncytial virus which is more attenuated in African green monkeys than the TS-1 respiratory syncytial virus mutant, and a pharmaceutically acceptable carrier, wherein the mutant is derived from 2B strain of respiratory syncytial virus.
