Abstract__ Background Two recombinant live attenuated human parainfluenza virus type 1 rHPIVi mutant viruses have been developed using a reverse genetics system for evaluation as potential intranasal vaccine candidates. These rHPIVi vaccine candidates have two non-temperature sensitive non-ts attenuating att mutations primarily in the P C gene namely CR84GHNT553A two point mutations used together as a set and CAi70 a short deletion mutation and two ts att mutations in the L gene namely LY942A a point mutation and LAi7i0-ii a short deletion the last of which has not been previously described. The latter three .
