摘要: PROBLEM TO BE SOLVED: To provide live, attenuated respiratory syncytial viruses (RSV) useful as vaccines against RSV infection and/or the development of severe RSV-associated illnesses.SOLUTION: The live, attenuated RSV is identified by continuous passage of hRSV A strain (Merck strain 287). The attenuated virus is nonpathogenic and attenuated to some extent when administered to the subject, but substantially retains the antigenic and immunogenic properties of wild-type RSV. A method for inducing a protective immune response against the RSV infection in the subject's body includes a step of administering one or more of immunogenic composition including an attenuated RSV population and a pharmaceutically acceptable carrier.
