Five temperature-sensitive (ts) mutants of respiratory syncytial (RS) virus (ts-1, ts-1 NG-1, ts-1 NG-16, ts-2, and ts-7), previously evaluated forinfectivity and virulence in chimpanzees and owl monkeys, were also assayed for in vivo genetic stability. None of the five mutants tested was completely
## Abstract Approximately 10^4^ plaqueโforming units (pfu) of five temperatureโsensitive (__ts__) mutants of respiratory syncytial (RS) virus were administered intranasally to seronegative chimpanzees to evaluate their level of attenuation. When the __ts__โ1 mutant was given to two chimpanzees, the
