Good result is a good news. Another study of real-world usage that has been running in England, organized by the UK Medical Research Council, came to similar results this year. But on the other part there is the fear that Truvada will encourage risky sex.. For the instant, the studies were mainly focused on men who have sex with men. It’s not clear how the drug will work in the real world among other high-risk populations, like injection-drug users. For Truvada to have a big impact, high-risk populations need to know about it and have access. Health education is needed on the way.
