Survival following vaccination with 38C13 Id adenoviruses versus Id-KLH protein.

Groups of 10 mice were vaccinated with a single IM injection of 10⁸ PFU Ad-IdhuCR (▴) or Ad-IdmuCR (▿) or 2 biweekly injections of PBS (○) or 38C13 Id-KLH plus QS21 adjuvant (■). Three weeks following vaccinations, mice were injected SQ with 1000 38C13 tumor cells and followed for survival. Results are representative of 4 individual experiments.
