或许人们极少听说植物可产生疫苗,然而目前英国正把由植物产生出的疫苗试验于豚鼠和小鼠,以观察这种疫苗是否会刺激动物产生抗口蹄疫的抗体。如果试验成功的话,此疫苗用于牛的希望将大大提高。利用植物生产疫苗要比其他生产方法便宜且简便易行。 Perhaps it is seldom heard that plants produce vaccines. However, at present, plants in the United Kingdom are experimenting with vaccines produced by plants in guinea pigs and mice to see whether such vaccines will stimulate animals to produce anti-foot-and-mouth disease antibodies. If the trial is successful, the promise of this vaccine for cattle will be greatly enhanced. Vaccine production using plants is cheaper and easier than other methods of production.
