    The Future of a Vaccine, and New Warnings for Asia (2)



    The report says prevention programs can be effective if governments invest at least thirty cents a year per person.For more than twenty years, scientists have been trying to develop a vaccine to prevent H.I.V. infection. The latest failures came last September. Researchers halted two studies of an experimental AIDS vaccine from the drug company Merck.

    Early results showed that the vaccine not only failed to protect, it appeared to put some people at higher risk of infection.

    Last Tuesday, several hundred researchers and activists met in Bethesda, Maryland, for a Summit on H.I.V. Vaccine Research and Development. They debated what to do now.Many of the scientists agreed that experimental vaccines should continue to be tested on humans. But many said there should be less dependence on human trials. 

    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.

    There also were calls for a return to more basic science, first identifying and answering major scientific questions. But Doctor Fauci said the search for an AIDS vaccine will not stop.

    报告称,如果政府每年向每人至少投资30美分,预防项目就会发挥作用。二十多年来,科学家们一直努力研制预防艾滋病毒感染的疫苗。最近的一次失败发生于去年九月份。研究人员中止了药品公司默克的两项实验艾滋疫苗研究。

    早期研究表明疫苗不但无法起到保护作用,而且还让一些人受感染的风险更高。
    上周二,数百名研究人员和活动家参加了人类免疫缺陷病毒疫苗研发峰会,会议在马里兰州的贝塞斯达举行。他们对现在该做什么有争论。许多科学家支持实验疫苗应当继续在人体上作实验。不过一些人认为应减少对人体试验的依赖。

    会议由国家过敏症与传染病研究所组织召开,其领导人安东尼·福奇和其他一些人认为,还需要作更多的动物实验,以此来补充人体实验所获得的发现。

    还有人呼吁回归到更多基本的科学知识上去,首先是确定和回答重大的科学问题。但是福奇博士说,寻找艾滋疫苗的努力不会停止。
