National Institutes of Health in the U.S. announced that it attempts to immunize volunteers with an experimental vaccine known as HVTN 505 is officially terminated, since it is clear that it does not prevent infection.

Clinical trial began in 2009 and since then, 1,250 voluntary participants received vaccine and 1244 others - control infusion of placebo, both groups over a period of 24 weeks. Among all the volunteers in total, so far has 41 infected with HIV than those who received the vaccine and 30 infected than those who received placebo. The study focused mainly people who have unprotected sex.

Vaccine strategy using "double whammy" that aimed to strengthen the immune system. Three initial injections are placed initially, and after 16 weeks - another injection containing genetic material which creates a molecule of the type produced by HIV in order to induce a response in the immune system against viruses. Scientists say the vaccine itself did not cause infection. After presenting the matter collected data and results collected until mid-April at the National Institute of Allergy and Infectious Diseases, which sponsored the clinical trial recommended stopping the attempt to create the vaccine. Volunteers will be monitored for 5 years, and the data will be analyzed for further information.
