The report says prevention programs can be effective if governments invest at least 30 cents a year per person. For more than 20 years, scientists have be trying to develop a vaccine to prevent HIV infection. The latest failures came last September. Researchers halted two studies of an experimental AIDS vaccine from the drug company Merck.
这项报告指出，如果政府每年平均给每人提供至少30美分，预防计划将会起到效果。20年来，科学家尝试开发一种预防HIV感染的疫苗。最近一次失败是去年九月。研究者终止了来自默克制药公司的两项实验性艾滋病疫苗的研究。
Early results showed that the vaccine not only failed to protect, it appeared to put some people at higher risk of infection.
早期的结果显示，疫苗不仅仅没有起到保护的作用，还会使很多人处于更高的感染危险当中。
Last Tuesday, several hundred researchers and activists met in B, Maryland, for a summit on HIV vaccine research and development. They debated what to do now. Many of the scientists agree that experimental vaccines should continue to be tested on humans. But many said there should be less dependence on human trials.
上周二，数百名研究者和活动家汇聚在马里兰州B市举办的HIV疫苗研究和开发的峰会上。他们讨论现在所要做的是什么。很多科学家都同意实验性疫苗应该继续在人类身上测试。但是很多人表示应该减少对人体实验的依赖。
Anthony Fauci is head of the national institute of Allergy and infectious diseases , which called the meeting. He and others said there should be more tests on animals, to add to discoveries from human studies.
美国国家过敏症与传染病研究所召集了这次的会议。AF是这个机构的领导。他和其他一些人表示应该更多的在动物身上实验，以补充来自人类研究的发现。
There also were calls for a return to more basic science, first identifying and answering major scientific questions. But Doctor F said the search for an AIDS vaccine will not stop.
还有人呼吁更多的回归基础科学，首先确认和回答主要的科学问题。但Ｆ博士表示，对艾滋病疫苗的研究不会停止。
