What is the conventional way to cure the malaria?
The fight against malaria may have taken a promising step forward with the latest tests of a new kind of vaccine, which aims to keep people healthy and prevent the infection from spreading.
(6)Most malaria vaccines under development work by including genetically engineered versions of just a handful of the thousands of proteins of a parasite that could cause malaria. Those modified proteins are designed to trigger an immune response to this parasite, after it’s passed into the host’s bloodstream by the bite of an infected mosquito.
(7)In contrast, says researcher Robert A. Seder of the US National Institute of Allergy and Infectious Diseases, this new vaccine includes a deactivated version of the entire parasite. " So instead of picking out one or two or three genes," he says, " you have the potential for what we call breadth generating an immune response that would be broad rather than narrower. And so that would be a good thing. "
选项
A、Altering genes of the parasite.
B、Controlling an immune system response.
C、Injecting parasite proteins into bloodstream.
D、Maintaining original parasite proteins.
答案
A
解析
本题设题点在方法途径处。根据句(6)可知,现在广泛应用的疟疾疫苗是通过变异几组数以千计的疟原虫蛋白质基因实现的。变异后的蛋白质通过受感染的蚊子叮咬传人患者血液中,以引起身体对这种特定寄生虫的免疫反应,故答案为[A]。
