Phase I study to assess safety, tolerability and immunogenicity of the hRVFV-4s vaccine in healthy subjects |
Humans |
hRVFV-4s is a four segments human Rift Valley fever virus vaccine, which derives from a natural clone (Clone 13) that lacks 69% of the gene NSs, a major virulence determinant of the virus. The hRVFV-4s vaccine is further attenuated by splitting the M genome segment into two M-type segments. |
