抗癌疫苗的临床试用最近在华盛顿召开的生物技术会议上，免疫工作者介绍了用新型疫苗治疗乳腺癌、前列腺癌和大肠癌的初步观察。他们采用新的生物工程技术，把癌细胞蛋白的基因克隆化，制成疫苗调动病人的免疫系统，以期消灭肿瘤。加拿大爱德蒙顿大学的免疫学专家Ｌｏｎｇ... Clinical trials of anti-cancer vaccines At a recent biotechnology conference in Washington, immunization workers introduced preliminary observations of new vaccines for breast cancer, prostate cancer, and colorectal cancer. They used new bioengineering techniques to clone the genes of cancer cell proteins into vaccines to mobilize the patient’s immune system in an attempt to eradicate tumors.
