Abstract excerpt
In an attempt to evaluate the level of attenuation of live parainfluenza type 3 virus (PIV3) vaccine candidates, we compared the responses of partially immune adult volunteers inoculated intranasally with 10(6) to 10(7) 50% tissue culture infective dose (TCID50) of bovine PIV3 (n = 18) or cold-adapted (ca) PIV3 (n = 37) with those of 28 adults administered 10(6) to 10(7) TCID50 of wild-type PIV3. The candidate...
