纽约时报2010年7月20日头条：非洲研究赋予女性抗爱艾滋病新希望
摘要：目前艾滋病疫苗仍远远供不应求，两项严格的新研究发现了两条不同的途径，可大幅度减少女性和女学生感染艾滋病病毒的几率。在撒哈拉以南的非洲，女性和女学生是新增艾滋病感染者的主要群体。在历经二十多年的研究未能找到有效阻断艾滋病病毒的杀菌剂之后，在南非两个艾滋病重灾区工作的南非科学家称，他们终于找发现了一种能够真正起到效果的杀菌胶。据称，与使用安慰药的女性相比，使用被广泛用于治疗艾滋病的抗逆转录病毒药物Tenofovir的杀菌胶者，艾滋病感染率要低39%。
African Studies Give Women Hope in H.I.V. Fight
VULINDLELA, South Africa – With an AIDS vaccine still out of reach, two rigorous new studies have found different ways to sharply cut H.I.V. infections among women and schoolgirls, who make up a majority of the newly infected in sub-Saharan Africa。
After two decades in which researchers searched fruitlessly for an effective vaginal microbicide to block H.I.V., South African scientists working in two AIDS-devastated communities of South Africa, one rural and one urban, say they have finally found something that shows real promise。
Women who used a vaginal microbicidal gel containing an antiretroviral medication widely used to treat AIDS, tenofovir, were 39 percent less likely over all to contract H.I.V. than those who used a placebo. Those who used the gel most regularly reduced their chances of infection 54 percent, according to a two-and-a-half year study of 889 women by Caprisa, a Durban-based AIDS research center. (节选部分)
