Education has a very important role in HIV prevention. According to the statistics of the Global Campaign for Education, the education prevents 700,000 new cases of HIV annualy ( HIV Interventions for Young People in the Education Sector , p. 2). It is very important to reach drug injectors at the street and at the places they congregate to maximize the chances of HIV prevention. Former or current users are used as peer educators to help people risky to HIV infection (United Nations Office on Drugs and Crime 2004 , p14). Trained peer educators who are themselves former or current drug users and sex workers are able to provide gender, age and culturally appropriate risk-reduction information to the peers (DiClemente R & Wingood G 2000, p. 377). Using current drug-users as peer educators has the advantage of them knowing the language of drug users and their needs. The major advantages are increasing trust and credibility and having an equal level of communication. More than that, it may help the outreach workers themselves by giving them knowledge and skills and allowing them to have the important role in the program (United Nations Office on Drugs and Crime 2004 , p. 31).It should be taken into account that current users may not be reliable. More than that, it may send a mixed message to some people when a current drug user is used as a model to give information about getting off drugs and preventing disease transmission (United Nations Office on Drugs and Crime 2004 , p. 32). In fact, such peer educators need the help themselves wanting to help to stop HIV. HIV positive youth also may be trained as peer educators. Peer educators work with adolescents who are at risk of HIV infection. It may be difficult to retain young peer educators from at-risk populations. According to 2009 statistics, 3.2 million young women and 1.7 million young men aged 15-24 years were estimated to live with HIV (UNAIDS 2011, p17). Regional estimates indicates that HIV prevalence among young people in sub-Saharian Africa remains much higher than in the rest of the world. There is a wide range of risks and vulnerability of HIV among young people. There are certain differences between risk and vulnerability. Risk is connected with behaviors (things which people may control such as using condoms) or situations (things which are impossible to control such as forced sex) in which there is a possibility to be infected with HIV (Kirby D, Laris B & Rolleri L 2006, p. 209). Risk is not connected with the factors described you as a person it refers to actions you are engaged in. Vulnerability is more subjective concept. The concept of vulnerability is connected with the likelihood of being exposed to a situation or behavior in which there is a risk of HIV transmission (Marshall B, Wood E & Shoveller J, 2011). People who live in developing countries such as Africa, Asia and Southern and Central America are more vulnerable to HIV infection due to their culture, religion and socio-economic factors (Rivers K & Aggleton P 2011, p. 4). Poverty forces the children of South Africa to have sex for money or goods. More than that, having a lot of sexual partners is considered to be popular and important among young men in Africa (Rivers K & Aggleton P 2011, p. 6). School programs avoid the sexual education and the teaching young people about condoms is prohibited in some countries of Africa (Rivers K & A
