An experimental AIDS vaccine has for the first time cuts the risk of infection in humans in what scientists on Thursday called a "breakthrough" in the quarter-century fight against the epidemic.
The vaccine reduced the chance of being infected by a third, researchers announced after the world's largest trial of 16,000 volunteers, carried out by the U.S. Army and Thailand's Ministry of Public Health. The surprising result comes after years of fruitless attempts by the medical world to find an HIV vaccine, including one trial jab that apparently boosted infection rates.
The vaccine was a combination of two older drugs that had not reduced infection on their own, and the researchers said they were now studying why the two apparently worked together. Researchers said the latest vaccine showed a 31.2 percent efficacy in reducing the risk of HIV infection.

வந்த வழி தெரியவில்லை... போகும் வழி புரியவில்லை
