天花的

Edward Jenner solve the problem of smallpox? He kept on focusing on people who had smallpox. He changed his way of thinking by turning to people without smallpox. Dairymaids advised that he use cowpox to experiment.

细节题。根据第一段第五句，他不再将注意力只集中在得天花的病人身上，转而开始研究那些不得天花的人，最终从挤奶女工身上发现了秘密，所以选不选。

The antigen of cowpox stimulates our white blood cells to memorize (不要写成: to remember) the specific antigen.

牛痘可以作为抵抗天花的疫苗，是由於牛痘和天花有著相同的抗原，所以我们的白血球不能区别它们(即以为它们只是相同的东西)。

Modified smallpox is assumed to have the same incubation period as ordinary smallpox, but to have a milder course of disease. The infectiousness of people with modified smallpox would be 33% of that for people with ordinary smallpox, with a case fatality rate of 10%. However, it would be harder to recognize modified smallpox and cases would be slower to withdraw to the home or go to the hospital than for ordinary smallpox. Before smallpox is recognized in the hospital (i.e., the first period), 75% of cases would be recognized on the fourth day of rash and the remaining 25% on the seventh day of rash.

Modified Smallpox一般是指比较近代的病例，同样的潜伏期，但疾病表现比较轻微，所以传染力也比较低，大概是典型天花的1/3左右，死亡率大概是10%，一般也比较不容易诊断，病例会比典型天花较晚才待在家里或到医院求诊，在病例发生发烧之后第四天产生小丘疹，到了发生疹子后的第四天，大概有75%的病例会被诊断，剩下的25%病例会在发生丘疹后的第七天被诊断。
