US authorities announced that they have halted clinical trials of an experimental vaccine designed to halt the virus that leads to AIDS after discovering it did not stop infection.

美國主管單位發現一款實驗性愛滋病毒疫苗無助預防感染後，宣布疫苗的臨床試驗喊停。

The program, which began in 2009, is the latest in a series of unsuccessful studies of candidate vaccines aimed at tackling HIV, the human immunodeficiency virus.

這項試驗2009年起展開，是一連串失敗的人體免疫缺乏病毒(HIV) 疫苗研究中最新的一樁。

The National Institute of Allergy and Infectious Diseases said volunteers in 19 US cities — either gay men or transgender people who had sex with men — took part in the study, with the HVTN 505 vaccine given to 1,250 and 1,244 receiving a placebo.

美國全國過敏症與傳染病研究中心表示，全美19個城市有2504人志願參加試驗，有些是男同性戀者，有些是和男性發生性行為的變性人。參與者中1250人施打HVTN 505疫苗，1244人施打安慰劑。

A panel analyzed the results of the study and recommended halting the program after findings indicated 41 infections among those who had received the vaccine versus 30 in the placebo group.

一個小組分析試驗結果，發現注射疫苗者有41人感染愛滋病毒，注射安慰劑者卻只有30人感染，因而建議停止試驗計畫。
